Rick and the group are facing down a gigantic horde of zombies which are held at bay by tractor trailers. The plan is to practice what they want to do tomorrow but all that is tossed out of the window when two of the trucks they are using as barriers crumble. The group scrambles to put the plan into action immediately, with each person taking on their responsibility. Only Carter is in doubt about what to do and if they can actually pull off their plan Rick orders the firing of flares into the horde. Zombies manage to push their way through another barrier.
The film now turns to black and white. Father Gabriel approaches Deanna, and she looks up at Gabriel with tears in her eyes and tells him that he was wrong.
Abraham carries the body of Deanna's husband wrapped up in a sack to prepare for burial. He puts down the body and takes a stiff drink and then pours some alcohol over the body. It's really a touching scene.
Jessie sits on the couch holding Sam with Ron by her side. Ron gets up suddenly and leaves the room despite his mother calling out for him.
In the medical area, Tara is awake when a bloodied Glenn and Nicholas stumble in. Glenn is pleased to see Tara alive. Eugene enters, clearly delighted to see Tara awake and comments that it's a good thing he didn't cut his hair. When Eugene continues to stare, Tara asks for Noah to protect her jokingly, not aware that Noah is dead.
Carl is sits next to Enid and she puts her hand on Carl's hand.
Morgan tells Rick that he was right that the threat wasn't over. Rick suggests that they talk more tomorrow. Rick explains that he doesn't take chances anymore and Morgan agrees that he shouldn't.
Sasha checks in on a drunk Abraham.
A walker stumbles down the road and gets the drive by treatment. Rick is still organizing his people as they continue to lead the walkers away from their small settlement. Rick reminds everyone to keep their heads in the game.
Back in black and white, Darryl is fixing his bike when Rick approaches. They talk about the guys Morgan met with W's on their head. Rick says that they need more watch points and that they don't need to go looking for new people anymore. Darryl is clearly conflicted about Rick's decision and admits that he doesn't agree. Rick believes that people out there have to take care of themselves just like them and heads to go and release Morgan.
Sasha and Abraham are driving together. Abraham checks in on how Sasha is doing and she questions if he was so worried, why he got into the car with her. Abraham doesn't answer, so Tara explains that doing something as big as this is living. Sasha stops her car when they reach the designated spot.
Back to black and white. Rick finds Morgan going through the paces with his fighting stick. Rick questions where Morgan learned this and Morgan explains that he learned it after everything. Rick apologises for having to do this but Morgan says that sometimes you are safer when there is no way out. Morgan adds that they need to get to know each other again.
Eugene is standing by the gate when Heath arrives with a group of people. Eugene is not anxious to let Heath in because he cannot confirm that Heath actually lives there. Heath doesn't have more patience and explains that the longer Eugene waits to open the gate, the more motivated he is to beat Eugene's ass. Eugene finally consents and opens the gate. Eugene explains that he just relieving Holly at the gate for now. Scott and Annie get out of the vehicle and introduce themselves. Heath asks if anything big happened while they were gone on patrol and Eugene suggests that Heath talk to Deanna to get it from the horses mouth. Heath starts to walk away and Eugene calls out that it's good to see someone like him and that he fully respects the hair game.
Rick is showing Morgan the community and explains that Reg built the gate. He tells Morgan that the community people didn't have to survive and have been behind the walls from the start. Rick is concerned that it's too late for the group to come around and suggests that Morgan talk to Deanna. Rick then notices that two graves are being dug - one for Reg and the other for Porch Dick. Gabriel tells Rick that he just wanted to help and Rick makes it clear that they are not going to bury killers inside the walls. Gabriel tells Rick that it's not his decision and Deanna intervenes to support Rick, adding that the trees should have the body. Ron watches the incident from a distance.
Porch dick is now loaded into a trunk by Rick and Morgan. Rick explains that he shot Porch Dick because Porch Dick killed Reg. Rick makes it clear that he has no sympathy for killers. It's Morgan who points out that Rick is a killer and so is he. Rick simply closes the lid to the truck.
Back in colour, Rick continues to talk with the group, checking their positions. There's an RV and a car in front of the gate and Morgan assures Michonne and Rick that it will hold. Morgan brings up the time that Michonne, Rick and Carl came to see him and asks if Michonne took one of his protein bars. Really? They're worried about zombies getting through the gate and Morgan is worried about the protein bar. Michonne lies and says no, but she did take the bar.
Ron walks under an underpass and climbs up a ravine. Morgan and Rick are walking and Rick suggests that they just leave Porch Dick there. Morgan tells Rick that this is not who he is but Rick tells Morgan that he doesn't know him. Morgan takes a few steps, drops his things and starts digging. The sound of walkers can be heard in the distance. Rick tells Morgan to stop and listen. They make their way to a cliff and when they look over it, they see a giant horde of zombies. Ron is running through the woods and is being chased by zombies. Fortunately for Ron, he runs into Rick and Morgan, who make quick work of the zombies.
Back in colour, Darryl rides his motorcycle down the street and is followed by the giant horde of zombies. Tara pulls out in front of Darryl and joins the grim procession.
In black and white, Rick, Morgan and Ron stare at the horde. Rick questions what Ron was doing out here and Ron explains that he wanted to know where his father was buried. Rick realises that the community still exists because the walkers which would have threatened it have been blocked into the area that they are facing. When Rick looks over his shoulder, he sees Ron walking away. Rick tries to tell Ron that he shouldn't be out here because he cannot protect himself, adding that if Ron comes out here he will die and turn into a walker. Rick demands that Ron return with them now, adding that Ron better not make it hard. Rick walks back with Morgan on his heels and he stops at the place where they dropped Porch Dick's body. While Ron watches, Morgan and Rick pick up shovels and start digging.
Back in colour, Glenn gets set up for his part of the massive zombie project they are undertaking. Glenn tells Nicholas to let one or two zombies out of the factory at a time so they can kill them. Heath expresses doubt but Nicholas tells Heath that Glenn knows what he is doing. Nicholas and Glenn manage to pry the door open to the factory but no zombies exit.
Back in black and white, Heath is talking about the zombie blockade and how he has never gone back to the area. Michonne realises that the walkers keep getting drawn in because of the noise. Rick then talks about the precarious position that they are in because the barricade will fall. Carol speaks out in support of Rick (note: Carol is still playing meek and mild) and Carter asks about building up the weak spots and offers to try and make it safe. Rick points out that building up the weak spots won't work because the sound the walkers make is drawing more and more walkers everyday. Deanna tells the group that they are going to do what Rick said. Rick starts laying out his plans and Sasha and Abraham offer to help. Rick says that they are going to have more people on watch from now on and asks for more volunteers. Michonne is the first to volunteer and Glenn whispers to Maggie that someone needs to watch Michonne because she is important and that people need to see her come back. Glenn then volunteers and when Gabriel offers to help, Rick immediately says no. Carter again expresses his doubts and asks if they should just fall in line behind Rick, after Rick waved a gun around screaming. Carter brings up the fact that Rick shot and killed Porch Dick but Deanna calls out enough. More volunteers start speaking up. When Nicholas starts to waver, Glenn shakes his head no at him but Nicholas volunteers anyway. Rick questions if Nicholas can handle this and Nicholas explains that they need people. Rick promises to keep this place safe. Carter asks to go through the plan again.
In colour, Rick, Morgan and Michonne fire off flares, as Darryl and Sasha continue to lead the zombies.
In black and white, Rick stands over a map and explains to Deanna, Michonne and Carter his plans. Carter however does not believe that the walkers can be drawn away. Eugene comes up with a suggestion to block the walkers in so that they don't get any strays. Carter again points out what he perceives to be a hole in Rick's plan.
In colour, Darryl and Tara continue to herd the zombies past the gate as flares go off. Morgan vigilantly watches the wall for any weakness as the herd begins to brush against the barrier. In the pressure of so many dead bodies, some zombies get crushed against the wall and others get trampled.
In black and white, everyone is working on shoring up the walls. Darryl approaches Rick and tells him that going out and finding more people is taking care of themselves before walking away. Carol approaches Rick next and offers him some water. Carol volunteers to help out saying that Darryl has been teaching her how to shoot. Rick tells Carol to stay back and get a feel for how people feel now because they have a long way to go with them. Carol says that they will get there because even though they think Deanna is in charge, Rick is now.
Glenn has come up with a plan to take on the zombies with Heath, while Nicholas stays back. I don't blame Glenn, I wouldn't entrust my safety to Nicholas. Glenn tells Nicholas that if things go south, his job is to draw the walkers away and then warn Rick.
Maggie approaches Tara and tells her that Nicholas lured Glenn into the woods and tried to kill him. Maggie then explains that Nicholas is the cause of Noah's death. Maggie brings up what happened at the prison and adds that now Tara is one of the most important people in the world to her. Tara promises to follow Maggie's lead and the two women hug, as Glenn watches with a smile.
In colour, a window in the factory is broken and as the walkers exit, Glenn and Heath start shooting. A walkers get his hands on Heath and Nicholas intervenes. The men manage to finish off the last of the walkers before moving on.
