Season 1 (TV Series)

Season 1 of The Walking Dead premiered on October 31, 2010 on AMC and BBC and concluded on December 5, 2010. The TV Series is based on the graphic novels of the same name by Robert Kirkman, Tony Moore and Charlie Adlard; it was developed for television by Frank Darabont, who wrote and co-wrote four of the season's six episodes and directed the pilot, Days Gone Bye, and also produced by Gale Anne Hurd.

Days Gone Bye
Wounded in the line of duty, King County sheriff's deputy Rick Grimes wakes from a coma to find the world infested by zombies. Alone and disoriented, he sets off in search of his wife and son.

Rick soon encounters two other survivors—Morgan Jones and his son Duane. Morgan explains that the undead are driven to eat the living. "One thing I do know, don't you get bit," Morgan says. Bites kill, then you become one of them. Morgan has seen the transformation first-hand. Morgan's wife, Jenny, was bitten then turned into a "walker." Now, she haunts him and his son by frequently returning to the house where she died.

Rick takes Morgan and Duane to the King County Sheriff's Department, where they stock up on guns and ammunition. Rick is headed to Atlanta where supposedly a refugee center has formed and the CDC is working on a cure. Along with a rifle, Rick gives Morgan a walkie-talkie with instructions to check in daily at dawn so they can meet up later. En route to Atlanta, Rick runs out of gas near a farmhouse, where he finds a horse to ride the rest of the way.

Meanwhile, Lori and Carl are living outside Atlanta in a camp with Shane Walsh, Rick's high school friend and partner, along with other survivors, including Amy, Dale Horvath, Jim, and the Morales and Peletier families. Believing Rick to be dead, Lori has begun a romantic relationship with Shane, who has become the group's de facto leader.

Guts
In a deserted Atlanta, Rick is overwhelmed by hordes of walkers who topple his horse and force him to retreat inside a tank. Guided by Glenn, an adventurous young man who instructs him via radio to make a run for it, Rick grabs a gun and a grenade and flees for his life. Glenn then leads Rick to a department store, where they meet up with other survivors: Andrea, Morales, Jacqui, "T-Dog" and Merle Dixon—a redneck ex-con.

Rick handcuffs the volatile Merle to the store rooftop after Merle attacks T-Dog. Rick then hatches an escape plan, which involves Rick and Glenn smearing themselves with "walker" guts as camouflage. Having navigated through the crowd of walkers, Rick drives off in a cube van to evacuate the survivors while Glenn lures the undead with the sound of a car alarm in a hotwired Dodge Challenger.

Back on the rooftop, T-Dog accidentally drops the handcuff key down a ventilation pipe, then chains the access door shut so that the stranded—and furious—Merle will be relatively safe from hungry geeks.

Tell It to the Frogs
Driving back to camp, Morales warns Rick about Merle's brother Daryl, who will be irate about his brother's abandonment. Glenn arrives at camp first, and Shane and Dale chastise him about drawing walkers with the alarm. Jim disconnects the alarm just as the cube van approaches.

Andrea tearfully reunites with Amy, her younger sister, as does Morales with his family. Rick then emerges from the van and is shocked to discover Lori and Carl living at this camp. The family is tearfully reunited. Later, around a campfire, Lori tells Rick she was told he would be medevaced to Atlanta. But it never happened. "Mom said you died," Carl says. "She had every reason to believe that," Rick replies before thanking Shane for saving them.

That night, Rick and Lori have sex in their tent, vowing to each other that this is a new beginning in their marriage. The next morning, Rick and the others find a walker feasting on a freshly-hunted dear in the woods. Jim theorizes the undead are running out of food in the city.

Daryl returns from an overnight hunt. After being informed of his brother's whereabouts, Daryl attacks Rick and Shane who quickly subdue him. Daryl then vows to retrieve his older brother, horrified at the idea they left Merle bound and unable to fend for himself. "I'm going back," Rick volunteers. Glenn and T-Dog also enlist.

"You're putting every single one of us at risk," Shane replies, arguing they need everybody to protect the camp. Rick contends that they really need the guns that he dropped when the geeks attacked. Lori is against it, but Rick tells her he has to get the walkie-talkie back, otherwise Morgan and Duane will walk into the same trap he did.

After Rick departs, Lori tells Shane to keep away from her family. "You are the one that told me that he died," Lori seethes. Nearby, an altercation breaks out between Ed Peletier and his meek wife Carol. After Ed slaps Carol, Shane intervenes and beats him to a pulp.

In Atlanta, Rick and company head to the same mall they left Merle at. Reaching the door they had barracaded they see the chains have been broken and find the rooftop deserted save for a severed hand lying, bloodied, beside a hacksaw.

Vatos
The Atlanta crew follows Merle's trail of blood down to the streets, but decide to retrieve Rick's guns before continuing the search. Glenn goes for the guns while the others stand guard. Their plan is derailed when Daryl is jumped by two men, who eventually take Glenn hostage at an inner city fortress that turns out to be a nursing home. Glenn is set free and Rick passes on some guns to the nursing home staff for protection. Rick, Glenn, T-Dog and Daryl then discover their vehicle is missing. "Merle," Rick says. "He's going to be taking some vengeance back to camp," Daryl predicts.

Back at camp, Andrea and Amy present fellow survivors with fish caught at a nearby lake. Dale interrupts the excitement to express concern over Jim, who is feverishly digging holes without explanation. Shane subdues Jim, who cannot remember exactly why he was digging: "I had a reason, don't remember," he says. "Something I dreamt last night."

Andrea, meanwhile, roots through Dale's RV looking for something to wrap up Amy's birthday present: a mermaid necklace she heisted from the department store. Later, the group feasts on fish around the campfire and the mood takes on a lighter note. When Amy steps away to go to the bathroom in the RV, she is bitten in the arm by an unseen roamer—one of many about to attack the camp. Rick and his cohorts arrive to drive the walkers back, successfully, though he is too late to save Amy or Ed. Jim is also bitten in the attack.

Wildfire
The survivors burn walkers' bodies, though Glenn insists they should bury their dead. Andrea cradles Amy nearby, unwilling to let anyone near the body. Dale commiserates, explaining that since his wife's death, "you girls were the first people that I cared anything for." Andrea tells Dale she feels guilty for missing so many of Amy's birthdays. "I'm sorry for not ever being there," Andrea wept kneeling next to a now re-animated Amy. She tells Amy that she's here now and loves her, then she puts her down with a shot to the head.

When Jim's injury is revealed and the sickness associated with infection worsens, Rick suggests the group go to the CDC for help. Shane thinks the Army base in Fort Benning is safer, but it is 125 miles away. While sweeping the forest for any remaining roamers, Shane tries to convince Rick to change his mind. "I've gotta do what's best for my family," Rick says. "If it was your family you'd feel differently." Enraged, Shane aims his gun at an unknowing Rick, but doesn't pull the trigger. Even though Rick may not have seen Shane's actions after their argument, Dale been watching the entire spectacle and mutters, "Jesus".

Later, Shane announces his support of Rick's plan. Morales says that his family will not be joining the group and they head off in a different direction. En route to the CDC, the RV breaks down. Jim, in agony, asks Rick to leave him behind. "I want to be with my family," he says of his late wife and children. The group reluctantly leaves him beneath a tree.

In a CDC laboratory, disheveled scientist Dr. Edwin Jenner performs experiments on tissue sample designated "TS-19". He then accidentally spills corrosive fluid initiating a decontamination sequence that destroys the samples. Meanwhile, Rick's caravan approaches the CDC. Jenner watches the group's approach via a security monitor.

TS-19
Jenner agrees to allow the survivors into the building, provided they submit to blood tests. The group then feasts on food and wine, then luxuriates in hot showers. Afterward, Andrea laments the fall of civilization as Dale attempts to comfort her.

Later, Shane drunkenly confronts Lori, professing his love and insisting he did not lie about Rick being dead. Drunk and out of control, Shane tries to force himself on Lori, who scratches his face and neck to stop him. Horrified by his own behavior, he flees, leaving Lori shaken and afraid.

The next morning, Jenner shows the group brain scans of Test Subject 19, his wife, who allowed her infection to be recorded. He admits he does not know what the disease is or how to treat it. Plus, he has lost contact with other facilities. Worse yet, the CDC's generators are running out of fuel. When they are empty, the building will self-destruct as per a decontamination protocol.

Though at first he tries to convince them to stay, Jenner agrees to let Rick and the others flee when the self-destruct is activated. Jacqui, terrified of ending up like Amy or Jim, opts to stay behind. After a fiery explosion, Rick and his fellow survivors caravan away from the smoldering rubble, destination unknown.
