Mercy

"Mercy" is the first episode of the eighth season of AMC's The Walking Dead. It is the one-hundredth episode of the series overall. It premiered on October 22, 2017. It was written by Scott Gimple and directed by Greg Nicotero.

Plot
Rick and his group, along with the Kingdom and Hilltop, have banded together to bring the fight to Negan and the Saviors.

Synopsis
Light plays across a sweating, seemingly exhausted Rick’s face.

Rick stands at the Hilltop graves, lost in thought.

Residents of Alexandria, Hilltop and the Kingdom prepare for battle at the colony; they prepare reinforcements and armour for their vehicles.

At the Sanctuary, a crossbow bolt pierces Dwight’s motorcycle tire. He unrolls the note that’s attached. It reads, “Tomorrow.”

Carol and Tara stand watch on a bridge. Tara checks the time. They spot a herd of walkers in the distance and smile.

Rick gives a rousing speech to the united communities, reminding them they’re fighting for their futures, for a bigger world. He vows to stop the Saviors and kill Negan, the only one who truly has to die. Maggie and Ezekiel echo Rick’s sentiments.

Dwight writes a response, secures the note to the bolt and shoots it back toward Daryl, waiting outside the Sanctuary.

Carol and Tara sit on the bridge and wait as the herd of walkers moves along the road below.

Rick sleeps in bed. His beard is full and white. Flowers sit on a nearby table. Hearing music, he wakes.

Carl searches a gas station for fuel. He comes across a nervous stranger who asks for help. Carl raises his gun, but the man insists he just wants food. As Carl is considering his request, Rick appears and chases the man away with a gunshot above his head. Carl tells Rick that hope will not be enough in their struggle against the Saviors.

Daryl and Morgan kill Saviors at various lookout points. One by one, they cross the targets off a list supplied by Dwight.

In Alexandria, Rick and other community members mobilize for an attack on the Sanctuary.

Daryl joins Carol, Tara and Morgan on the highway.

Rick leaves Alexandria with a caravan of vehicles that have been retrofitted for battle. Rosita watches from her porch, still recovering. Michonne and Carl stay behind. As they watch the procession of vehicles, Michonne tells Carl that this is his show; Alexandria’s safety is in his hands.

En route to the Sanctuary, Rick comes across a lone Savior on watch; he stabs the man and sifts through his belongings. The injured Savior taunts Rick, telling him that he will kneel again before the Saviors, and that his son will die. Angered, Rick frees a walker tethered to a nearby electric post and leaves it to feast on the dying man. He then signals the caravan to proceed.

The caravan arrives in a large field, where members of all three communities are waiting. Maggie insists on joining the initial phase of the fight, despite being pregnant. Ezekiel offers to let Maggie see the Kingdom’s doctor, but Jesus assures him they’ll retrieve Doctor Carson, who was previously taken by the Saviors. Rick vows to relinquish leadership and follow Maggie after the fight is over.

Carol, Daryl, Morgan and Tara wait on the highway until the herd arrives; they vacate the road in haste. Moments later, the SUV they parked on the exit ramp explodes. Dwight dispatches a large team of Saviors to investigate the explosion. Daryl and Morgan rig a tripwire across a road. They join Carol and Tara on a pedestrian overpass.

Rick’s group guns down two sniper lookouts at the Sanctuary as Dwight nochalantly walks inside. The caravan arrives at the front gate, parking in formation to create a wall with the metal sheets retrofitted onto each vehicle. Maggie gives the signal and the group raises their guns toward the sky, shooting in unison. Negan steps out with his lieutenants.

Light plays across Rick’s face. He looks up at a stained glass window.

White-bearded Rick gets out of bed and finds Michonne in the dining room of their Alexandria home. He walks over to her with his cane, a noticeable limp in his stride. Carl joins them.

Rick tells Negan’s lieutenants — Dwight, Simon, Gavin, Regina and Eugene — that he will let them live if they surrender. No one accepts his offer.

The group on the overpass spots a walker nearing the tripwire.

Negan tells Rick that he lacks the numbers to win a fight against the Saviors. At Negan’s command, Simon brings Gregory outside. Gregory declares that the Hilltop stands with Negan and the punishment for fighting against the Sanctuary is banishment for the offenders and their families. “The Hilltop stands with Maggie!” Jesus shouts.

Morgan kills the stray walker endangering the tripwire and sees the caravan of Saviors in the distance.

Simon pushes Gregory down the stairs after deciding he’s no longer useful.

On the road, the Savior caravan trips the wire and sets off an explosion.

The explosion is heard at the Sanctuary. Rick tells Negan’s lieutenants to make up their minds; he begins firing when they don’t respond. Negan’s crew runs for cover in different directions. Rick’s group continues firing, blowing out the Sanctuary windows. The herd approaches, drawn by the explosion. Morgan and Tara get in a car, preparing to leave. Carol urges Daryl to be careful.

Rick’s group continues to spray bullets at the Sanctuary, then retreats to their cars for evacuation.

Daryl shoots a succession of explosive barrels while riding his motorcycle toward the Sanctuary, guiding the herd.

Gabriel positions the RV in front of the Sanctuary fence, and exits as it continues slowly moving forward. Rick uses the garage door opener to detonate the explosives in the RV, successfully breaching the gate. Negan takes cover behind a vehicle, as Rick continues firing at him. Gabriel urges Rick to evacuate. Before he goes, Rick uses an instant camera to snap a picture of the scene. Rick leaves as the herd closes in on the Sanctuary; Gabriel gets in his car, ready to follow suit. Just then, he sees Gregory crying for help and runs to his aid. Gregory jumps into Gabriel’s car and drives off, abandoning him.

Carl returns to the gas station and leaves two cans of food with a note, “Sorry.” The mysterious man watches from the bushes.

Rick’s group waits for Gabriel at their rendezvous point. Rick tells Daryl that Gabriel stayed behind to save him, but they can’t wait for him any longer. Daryl signals the group to get back in their vehicles. They prepare to enact the next phase of their plan.

A small group stands outside the fence of the satellite station outpost they previously cleared out. It has since been re-settled by Saviors. Morgan asks Dianne if she’ll be able to hit the guards through the fence using her arrows. She expresses doubt.

At a second Savior outpost, Daryl and Rick shoot a guard at an office complex and enter the front gate.

Carol and Ezekiel lead a group toward a third Savior outpost. They gun down the Saviors outside the industrial building.

Meanwhile, Walkers continue to flood into the Sanctuary's grounds. Gabriel takes cover inside a trailer only to find it already occupied by Negan. Walkers surround the trailer as they swarm the Sanctuary.

Judith, now a child of 6 or 7 years old, runs up to white-bearded Rick in the kitchen. They walk to the porch and see people setting up a festival across the street.

Lights dance on Rick’s face.

Rick concludes his speech to the unified communities. He urges them to fight for tomorrow, assuring them they’ve already won. The crowd cheers, ready for battle.

 * This episode contains references to the first episode:

 * Gabriel being surrounded by walkers in a trailer with Negan is similar to Rick being surrounded by walkers in a tank.
