"30 Days Without An Accident"
Rick walks outside to the scene of a sunny, calm day. He splashes water on his face, and the shot pans out to a vegetable garden towards which he is headed. Lining the gates of the garden lie a dozen walkers that have accumulated overnight. While listening to music and digging in the garden, Rick finds a handgun, which he examines for a moment and then tosses into his wheelbarrow.

Carl walks towards Rick, complaining that his father had not awakened him. Rick says he had not done so due to the knowledge that Carl was up late reading comic books, and the two share a chuckle. Carl speaks of a pig that he calls Violet, laying in the corner of a pen, mentioning it looks ill; Rick tells Carl he should not name the pigs as they are food, yet answers that he does not know the reason of the pig's illness.

In the outdoor confines of the prison, Carol cooks breakfast for the residents. Daryl joins her, while numerous survivors thank him for his hunting including a young man named Patrick. A group of survivors, along with Karen, are clearing walkers that have built up along the gate perimeter. Tyreese approaches Karen (whom he calls "Beautiful"), telling her of his discomfort with killing walkers along the gate due to the face-to-face combat. Karen questions why he volunteers to help along the gates, to which he responds he wanted to get to know her better. Tyreese tells her he's going on the supply run; Karen gives him a good luck kiss, and tells him to be careful. Meanwhile, Hershel is telling Rick about planting more crops when Michonne arrives from a scouting run. She volunteers to check the traps for any animals before the walkers get them but Rick decides to go himself. As he leaves, Hershel tells Rick that their council (himself, Glenn, Carol, Daryl, and Sasha) preferred that Rick take his gun along when he goes outside the gates for protection.

As the supply group gets ready to leave, Zach meets up with Beth and the pair kiss each other goodbye. Bob volunteers to go along to earn his keep; after some hesitation, Sasha allows him to come. As they reach an abandoned army camp around a shopping mall, Daryl asks them to listen to the music booming in the distance and notes that he had been part of a group that hooked it up to car batteries to draw the walkers away. The group approaches the front of the store and Zach starts a conversation with Daryl, trying to guess what Daryl's pre-apocalypse employment was. They mention this had been going on daily for the the past six weeks. Zach guesses a homicide cop and Daryl affirms the guess. An incredulous Zach apparently doesn't believe it and states he will keep on trying to guess. In the store, Bob approaches a wine/beer aisle in the store and is tempted to take a bottle. He decides to put it back, causing the entire shelf to tip over and fall on him, pinning his legs. This also attracts the attention of walkers on the roof who begin to fall through the worn and decaying ceiling. Daryl and Zach are able to free Bob, but Zach is bitten in the process. The rest escape as a wrecked helicopter falls through, landing on Zach and destroying the mall and any remaining walkers.

Meanwhile, Rick is checking the traps when he encounters Clara. Initially mistaking her for a walker, he is startled when she calls out to him pleading for help. She asks if he is with a group and begs him to take her and her husband, Eddie, with him. Rick tells her that if they answer three questions to his satisfaction, he will and she leads him to her camp. As they approach the campsite, she states "It is just a head." As she crouches over a small suspicious bundle, Clara suddenly attacks Rick and after he sidesteps her, she stabs herself in the stomach. Clara tells Rick that she could not stand living without Eddie and so she took him with her. Clara, in a state of delirium, pleads with Rick not to kill her so she can remain with Eddie in a zombfied state. They do not show Eddie's body or what is in the bundle, although as Rick walks away, the camera closes in on the bundle, which is moving about and grunts come from it. The bundle is no bigger than a human head.

After arriving back at the prison, Daryl tells Beth what happened to Zach. She says that she doesn't cry anymore but hugs Daryl. She then resets the tally she was keeping of days without accidents. Patrick, who wasn't feeling well earlier, is seen coughing heavily as he goes to the showers. After a few seconds, he then collapses on the floor and reanimates soon after.

"Infected"
Late at night, a mysterious figure is shown feeding a rat to the fence walkers. The scene then swaps to Tyreese and Karen in their cell, overlooking their lives and then Tyreese begins singing to her. Karen then roams out of the cell and into the showers, where she hears movement but finds nothing. After she exits, a zombified Patrick rises out of the shower, undetected. He exits the showers and follows her back to the cell block. He stops at Karen's room, but is distracted by the coughing of another person and wanders into his cell and proceeds to bite the man's throat, preventing him from calling out for help.

After Patrick leaves, the man soon awakens as a walker. Rick and Carl head out to tend to the pigs and Carl asks if he can help with the fence cleaners, but Rick shuts the idea down. Carl apologizes and assures Rick that he is trying to live normally and asks if he can have his gun back. Before Rick can answer, they hear gunshots. Mika and Lizzie Samuels run out of Cell Block D, screaming for help. A horde of walkers have attacked from within and have killed several people. Michonne, who was heading out on a supply run, is alerted of the chaos but gets trapped in the prison gates with two walkers. The walkers overpower her, but Carl kills one of them; the other one was kicked off by Michonne and shot by Maggie. Michonne accidentally cuts herself on one of the snares, but is helped up by Maggie and Carl. In the cell block, the group clears out the walkers. Carol assists Ryan Samuels into a cell after he is bitten on the arm and prepares to amputate it before realizing that he has been bitten on his nape as well. After the threat temporarily clears out, Daryl and Rick comb the area, searching for any lifeless people to mercifully put-down when Glenn gets attacked by a walker. Daryl is able to shoot it in the head, and realizes that it was Patrick. Another bloody-eyed walker, Charlie, emerges from a cell and is put down by Rick.

Rick, Hershel, Dr. Subramanian, Daryl and Bob gather around Charlie's body, noting that he has no bites or scratches. Subramanian recognizes the blood pouring out of Charlie's orifices as an indicator of disease, and Rick mentions the bloody-eyed walker, Violet, and the sick boar he encountered. Subramanian explains that flu's like the one that killed Patrick were spread by pigs and birds in the old days and thrive in close quarters, like the cell block. They conclude that everyone in the cell block could be infected by the disease.

Ryan realizes that he is dying, and asks Carol to take care of Lizzie and Mika for him as if they were her own. Carol agrees, but tells him that he has to let them say goodbye to him before she kills him. As Lizzie and Mika say goodbye, Carol tells them what she has to do but Lizzie volunteers to do it instead. At the last minute, she is unable to stab her father in the head and turns away crying as Carol takes back the knife and does it herself.

Carol, Hershel, Daryl, Sasha, and Glenn think of what to do with the people who might have been infected when they hear coughing outside the room. It's shown to be coming from Karen, who was walking by with Tyreese. She is told that she must be quarantined while they find out what the cause is. Sasha (as well as Karen herself) calms Tyreese, saying that it's necessary. As she leaves, Karen also mentions that David was coughing as well. Carl and Maggie are carrying Michonne back inside when Rick approaches them. He tells them what happened and assures Maggie that Hershel and Beth are fine. He says that they must stay away from him for now due to possibly being infected.

Beth is seen dressing Michonne's wound when the latter says that she made a mistake letting the two walkers get the better of her. She bitterly says that Maggie and Carl should have left her. Beth says, "Now THAT is foolish. People getting hurt is part of living with a group." She muses about those who died, wondering what you call a parent who's lost a child. Michonne begins to tear up but composes herself immediately and Beth doesn't notice. Later, she asks Michonne to hold Judith while she cleans up the mess Judith made on her. Michonne looks at Judith with indifference but then loses control and weeps while holding Judith close.

Daryl is digging graves for those who died when Rick comes by to help. Daryl tells Rick that he's earned his time away from being in a leader position when Maggie screams for them to follow her; it's shown that a massive group of walkers are converging at a portion of the fence that is about to give way. Despite the efforts of them, Glenn, Sasha and a few others, there are just too many. Sasha points out the carcasses of several dead rats near the walls, suggesting that someone's been luring the walkers to the fence. Rick, getting an idea on what to do, tells Daryl to get one of the trucks. The two lead the walkers a few meters away and Rick pulls out one of the piglets; he then cuts it on the back and leaves it for the walkers to devour. They repeat this several times before the walkers are a safe distance away.

Meanwhile Carol, who promised Ryan to look after Lizzie and Mika, finds them near the fence looking at walkers. Carol, who was told earlier by Mika that her sister was 'funny in the head', assures her that she needs to be strong in letting her father go and not to run away from her fear of the walkers but to face them.

Carl finds his father chopping up the pig pen. Rick explains that they either got the virus from the pigs or that 'we infected them.' He tells Carl that they need to stay away from Judith for awhile to protect her from possibly getting infected. He then pulls out his gun and holster as well as handing Carl his gun back. He lights a match and burns the pigpen; then, Rick takes off his bloody shirt and throws that into the fire as well. Tyreese is seen going to Karen's isolated cell in the tombs with some flowers. He notices a trail of blood leading down the hallway; following it, he's led outside where he sees the burnt and charred corpses of both Karen and David.

"Isolation"
In the inner courtyard, Tyreese explains to Rick, Carol and Daryl how he found Karen and David burnt corpses;  he came to see Karen, saw the blood trail on the floor and it led him outside. Tyreese demands Rick to find who did it and bring the killer to him; when the latter tries to calm him down, he turns violent and attacks Rick, punching him in the face. Daryl holds him up, and Carol tries to stop Rick from retaliating, but it's too late. Rick charges at Tyreese, knocking him down and brutally beating his face. Daryl eventually pulls Rick off Tyreese before it goes any further. Rick looks at his severely injured hand, horrified with what he just did.

Dr. S and Hershel are looking over a bite victim who got his arm amputated. Unluckily, the victim dies of blood-loss. Later, Hershel is bandaging Rick's hand. He comments on the group's situation, and that "everything they worked so hard to keep out just found its way in" and briefs Rick of the flu situation; it is spreading and that another council meeting is being held the next day to decide what they should do. Tyreese is seen digging graves for Karen and David. Bob approaches him, telling Tyreese to go see Hershel and make sure he's alright. Tyreese firmly says that he will only after they are buried. Bob tries to change his mind, but Tyreese glares at him and repeats "once they're in the ground."

Glenn suggests to Hershel that with Karen and David dead, the infection may have been curbed. Sasha suddenly leaves C-Block, exhibiting the clear symptoms. She assures Hershel that she'll go to A-Block, where all the sick people are being isolated, to see Dr. S, who is revealed to be sick as well. At the meeting the following morning, the council eventually reach the consensus that they need medical supplies for treatment. As Hershel mentions that there is an animal hospital facility nearby that could help, Glenn starts to show symptoms of the flu.

Outside, Carol is pumping the water, pointing out to Rick that they are running low. They agree that the next day they will go out to clean the cistern. She suggests to Rick that he should talk to Tyreese, before leaving back to the Prison. Rick cautiously approaches Tyreese who is finishing the graves. He says he's sorry for hitting Tyreese, and then proceeds to ask him if Karen and David had any enemies or anyone who had a problem with them. Tyreese fiercely denies this then walks off, mocking Rick for spending the day "looking at water pumps" instead of trying to find the murderer.

In the cell block, Rick briefly talks to Carl to look over the office block, where the most vulnerable survivors are being kept at; the kids and the elderly. Back in A-Block Tyreese, who's there watching the sick (making sure no one will try to kill them), is asked to join the supply run for medical supplies with Daryl, Michonne and Bob. He refuses at first, but Daryl is able to convince him otherwise, saying he'll help them more in the run, looking for medicine than there, watching. He bids farewell to a sick Sasha, and leaves with the team.

In the office block, Hershel decides to go into the woods, hoping to find herbs to treat the patients. After a tense moment with Carl saying he can't leave, they both go out. Outside, Hershel comments that he'd be good without him, and remarks how peaceful it is out there. How safe is out there compared to the Prison. Carl denies, pointing out to a nearby, severely-decomposed walker, and soon one more shows up. They leave the place with the herbs, with Carl remarking how peaceful it was.

Arriving back at the prison, Maggie sees Hershel entering A-Block and warns him of the sick. Rick overhears the arguing and sides with Maggie. Hershel then proceeds to remind them how they risk their life everyday and every hour, no matter what they do. He says that it isn't their choice; the only choice being what they are risking it for. Stating he can help the sick, Hershel pulls his bandana over his face and goes into the cell block. He gives Dr. S the herb tea. Suffering heavily from the symptoms, he coughs blood which sprays Hershel's face. Aware that he's most likely infected already, Hershel takes off the bandana and wipes his face. He also treats Glenn, giving him encouragement to keep pushing through.

While driving towards the hospital the supply run, the group hears a voice over the car radio repeating the word "Sanctuary... Sanctuary..." Daryl is distracted by it and hits a few walkers on the street. He stops the car, shocked at the massive herd of thousands of walkers between them and their destination. Daryl drives in reverse and runs over several more walkers but the car eventually gets stuck, forcing them to go the rest of the way on foot. Daryl, Michonne, and Bob make it out, but Tyreese stays behind, not noticing what's going on. Bob eventually snaps him out of it and Tyreese storms out of the car and in a rage, ferociously begins to kill the walkers that are quickly surrounding him. After running in the woods for a while, the group stops to rest, and notices movement in the bushes. Tyreese comes out, covered in walker guts and blood, but alive and unscathed.

Outside, Carol rigged a distraction for the walkers and is beyond the fences cleaning the cistern. Rick notices this and runs towards her. At the same time, several walkers emerge from the forest behind Carol at the same time a few of the walkers at the fence turn their attention towards her. After a few seconds, Carol finishes cleaning the hose and Rick is able to save her. Thy both run back towards the fences and make it back inside. Rick tells her that what she did was stupid and careless. As she walks away, Rick tells Carol that he's noticed how far she'd go to protect the group of survivors. He then asks her if she killed Karen and David: after a moment, she responds to him: "yes" and walks away.

"Indifference"
Carol is talking to Lizzie, telling her that she is going on a supply run with Rick. As Carol talks to Lizzie, Rick roams the room where Karen was previously held. Rick imagines Carol stabbing Karen in the head and dragging her body down the hallway to be burned.

As they prepare to leave, Daryl and his supply-group continue to walk to find another vehicle, as they were forced to ditch their former one, due to a massive herd. They then find an autoshop with a few walkers and decide to clear it out after finding a usable car.

As the group chops away at the overgrowth, Tyreese, still unhappy with Karen's death, cuts too fast and pulls at a door, releasing the autoshop's walkers. The group clears them and heads in to search the area for a battery.

Carol and Rick search a house, finding several supplies. A walker comes out, falls down the stairs, and Carol kills it. Soon after, Sam and Ana come out from their hiding place. Carol fixes Sam's dislocated shoulder, and Rick asks them a few questions. Rick and Carol then go out to the yard to find several tomatoes. As they continue to move, they suddenly find a basket with dropped food, and then find Ana's leg. At the distance, they see what is left of Ana being consumed by two walkers.

While scavenging the veterinary college for medical supplies, Daryl and his supply-group are ambushed by walkers who have seemingly died from the same flu-like disease present in the Prison. Tyreese helps the group escape by throwing a fire extinguisher through the window and they all jump onto the roof of an outside walkway. Bob almost loses his bag but retrieves it. Daryl finds there is nothing in his bag but a bottle of liquor, which he attempts to throw away. Bob puts his hand on his holster, pleading with Daryl to give him the bottle back. Daryl, unintimidated, disarms Bob and grabs him until Tyreese breaks them up, saying that Bob has already made his choice. Daryl says that they should have never allowed Bob into the prison group, and that he will beat him into the ground if he drinks even a sip of liquor before the sick prisoners take the medicine.

Rick gives Carol her supplies, food, and a vehicle before isolating her from the group, believing that nobody will trust her (including himself) once they find out the truth about Karen and David's deaths, Tyreese would have probably killed Carol. Carol hands him a watch that Ed gave her on her anniversary before driving away.

"Internment"
Rick arrives back at the prison and meets Maggie. He tells her what happened to Carol, and she agrees that she would have done the same. Rick heads to the administration building, where he gives a bag of food to Carl. Inside A Block, things get worse when a few more members get sick. Hershel notices that Sasha is passed out, and he revives her. Hershel goes to check on a father, who's teenage son is dying in his cell. Soon after, two walkers leave their cells. Lizzie calls for help, which gets the attention of a walker behind Hershel. Hershel is pinned by the walker, but the father and a woman come to his aid. However, the father's son turns and attacks his father from behind, to which he accidently fires a gunshot that kills the woman. Hershel gets up and runs toward Lizzie, who gets pinned by a walker. He manages to throw the walker off of the catwalk. Next, he goes to get the shotgun from Dr. S, however he has already turned. Hershel kills him, but right after climbs onto the metal fence that the walker from before landed. He ends up getting pinned. Outside, Maggie and Rick hear a gunshot, to which Maggie and Rick runs inside. Rick gets to the administration building, where he gets Carl to come help him with the fence. Maggie makes her way to A Block only to find it locked. She heads to the visitors room and smashes a window to get into A Block. She kills the walker that pinned Hershel and the two head to help Glenn who has stopped breathing. Outside, the fence gives way and a hoard of walkers get in. Rick and Carl run into the courtyard, where they get assault rifles and gun down the many walkers. Right after they finish, the van with Daryl, Michonne, Tyreese, and Bob arrive. Daryl and Michone run out of the van to go help, while Bob and Tyreese head to A Block. Tyreese goes and cradles his sister in his arms, while Bob goes to administer drugs to Glenn. Outside, The Governor is seen looking at the prison from a distance.

"Live Bait"
In a flashback, The Governor flees after his massacre of the Woodbury Army, alongside with his two remaining henchmen: Martinez and Shumpert. They later set up camp at the military outpost where they ambushed the National Guardsmen months earlier. The Governor is sitting in front of a campfire, when a female walker approaches him. She falls into the fire, and proceeds to crawl towards him, whereby Martinez shoots her in the head. Martinez notes that Philip didn't even react to the walker approaching him or the subsequent gunshot. The following morning, he and Shumpert decide to abandon The Governor, leaving the latter to fend for himself. He then drives back to Woodbury and burns down the entire town. After several months of surviving the elements, he finally collapses on the street. Philip then notices a little girl in a window of an apartment building. He pulls himself back to his feet and investigates. He finds the Chambler family residing inside, consisting of two sisters, Lilly and Tara, as well as Lilly's daughter, Meghan, and their father, David. They, at first, warily hold him at gunpoint, but then they indulgently lead Philip to one of the adjacent apartments, after confiscating his pistol.

After hearing how Philip has survived the last few months, they ask him how long he plans on staying. He replies, "Just for the night." They also ask him his name; he replies that it's Brian Heriot (a name that he saw in paint on a barn while walking). Later, Lilly comes and offers Philip some food; he accepts but after she leaves, he scrapes the food off the plate and out the window, and then begins to eat a can of tuna he found. He goes and returns the plate and is invited inside. Philip sits down, as he watches Meghan and David play a makeshift game of backgammon. After the two sisters try to help David get up, Philip carries the elderly man to his room. David asks Philip to do him a favor and get the backgammon set that Bill Jenkins, one of his war buddies, had in his apartment up on the floor above them. Philip ventures and finds both the backgammon set, as well as a few rounds of ammo. He then hears a noise from the bathroom and finds an undead Bill lying in the tub. Philip mercifully kills him, and notices a revolver in Bill's hand, which he takes from him. He returns to the Chambler's apartment, and gives David the game and leaves.

The following morning, Lilly comes by to give Philip his gun back and wakes him. When offered back his gun, Philip tells her to keep it and reveals the revolver that he took. Lilly asks him for one more favor before he leaves. David has lung cancer and his current oxygen tank is nearly empty, so he needs a new one. She tells Philip of a nursing home located nearby and asks him to grab one or two. Philip makes his way there. He encounters several walkers, but avoids them. Finding a cart of oxygen tanks, he begins to leave but more walkers appear. After several struggles, he is able to escape the walker-infested nursing home with two tanks. Lilly thanks him and cleans a minor head wound that Philip received. She lets Meghan stay and watch him while she goes back to their apartment. Meghan asks Philip how he got the eye patch. Philip claims that he was a pirate and they both laugh. He says that he'll tell Meghan the truth but only if she doesn't tell anyone.

Later, Philip is teaching Meghan how to play chess when Lilly reveals that David has died. Philip tells them to leave, but Lilly wants another minute alone to say goodbye. David reanimates and nearly bites Tara, but Philip is able to save them by bashing David's head with the very oxygen tank he brought from the nursing home.

After David is buried, Philip burns the old photo of his wife and daughter. That night, he goes to say goodbye, but Lilly insists that he stays. Philip says that they can't go with him, but Lilly reveals that she saw the photo of his family. She further admits that they aren't like his old family, but that Philip has become a part of theirs. They leave the building in a delivery truck parked outside. After camping at a lake, their vehicle breaks down, forcing them to abandon it and continue on foot. Philip and Lilly sleep together, beginning a relationship. Down the road, Tara ends up injuring her leg. Philip goes ahead and, seeing a group of walkers, orders them to drop their bags and run. While the rest flee, Meghan is frozen in place and Philip convinces her to run to him. He then picks her up and leads the others through the woods. As they reach a clearing, Philip and Meghan fall into a dugout pit and find several walkers inside. Meghan cowers in a corner of the pit, as Philip kills the walkers. During this scene, gunfire can be heard in the background, and stops soon after the walkers are dead. Philip hugs Meghan and swears on his life that he will keep her safe from anything that may harm her. "Cross my heart," he tells her. He then hears a surprised voice coming from outside the pit. He looks up and sees a bewildered Martinez standing above him. Philip repeats "Cross my heart" as he strokes Meghan's hair, staring up at Martinez.

"Dead Weight"
A new and scary chapter is unfolding at a camp outside The Prison. Will peace be attainable with the addition of new members?

"Too Far Gone"
After things begin to calm at the prison, Rick and the group face imminent danger.
