Rick, Daryl, Tyreese, Sasha and Noah leave for Atlanta. As Carl and Michonne board up more windows, Gabriel furiously scrubs at the floor, trying in vain to remove the blood stains left by the massacre of Gareth's crew.
En route to Atlanta, Tyreese tries to console Sasha about Bob's death. "Don't," she says.
Elsewhere, Eugene lies in the road, still unconscious from Abraham's beating. Abraham kneels nearby, glaring silently ahead. Rosita tries to give Abraham water but he swats it away, then stands and looms menacingly over her. Maggie levels her gun at Abraham and orders him to sit.
Inside an Atlanta warehouse, Rick plans an attack on the hospital. Tyreese suggests an alternate plan: kidnap two of Dawn's officers and arrange a prisoner exchange. Rick is skeptical that the plan will work, but agrees to it after Daryl lends it his support.
Back at the church, Carl lays weapons in front of Gabriel and urges him to pick one for self-defense. Noting Gabriel's distress over the massacre, Carl reminds Gabriel that Gareth and his men were liars and murderers, and Gabriel reluctantly picks a machete.
At the hospital, Beth listens in as Officer O'Donnell suggests that Dawn pull Carol off life support in order to save resources. Beth protests, but Dawn sides with O'Donnell.
After O'Donnell leaves, Dawn privately instructs Beth to save Carol on her own and gives Beth the key to the drug locker. Then Dawn receives a walkie-talkie dispatch from Officer Shepherd about nearby gunshots and tells Shepherd to investigate with Officer Lamson.
Back on the road, Maggie stays with Eugene and Abraham while the rest of the group goes to replenish their water supply at a nearby creek. En route, Tara defends Eugene for being weak and defenseless. "He had one skill that kept him living," she reasons. "Are we supposed to be mad at him because he used it?"
Near the truck, Maggie builds a tent over Eugene to shield him from the sun. She then storms over to Abraham, who's still kneeling catatonically. "Get over yourself," she says. "You're not the only one who lost something today."
At the hospital, Beth visits Dr. Edwards and asks him what medication he would administer to Carol. He advises five milligrams of epinephrine.
Upon discovering that the creek water is polluted, Rosita creates a water filter using a technique she learned from Eugene. To everyone's surprise, Glenn spots fish in the creek.
Meanwhile, Shepherd and Lamson investigate the gunshots and find Noah in an alleyway. As they grab him, Rick's group ambushes and holds them at gunpoint. But a hospital car with another officer, Licari, screeches onto the scene and rescues Shepherd and Lamson. Rick's group opens fire and chases the officers, eventually catching all three.
Rick's group brings the captured officers to the warehouse. Shepherd explains that their hostage plan won't work because Dawn does not consider them valuable on account of their ongoing plot to overthrow her. Lamson, however, assures Rick the trade will work if they talk to Dawn in the correct manner. "Let me help you," he offers, claiming kinship with Dawn.
At the creek, Glenn, Rosita and Tara kill walkers and shred their clothes to create a fishing net. After successfully catching a fish, Glenn tells Rosita that wherever their group winds up, they're going to need her skills, and asks if she's in. "I'm in," she says.
At the church, Michonne checks on Gabriel in the rectory. He feigns fatigue and excuses himself. Alone again, he resumes his task: prying up floorboards with his machete, wanting to leave the church in secret.
At the hospital, Beth enlists an aide to create a diversion while she steals epinephrine from the drug cabinet and administers it to Carol.
Back at the church, Gabriel escapes by lowering himself underneath the floor and into a crawl space. Outside, he accidentally steps on a nail, but then hobbles undeterred into the woods.
At the warehouse, Lamson counsels Rick on negotiating with Dawn. He explains that Dawn will initially balk at the hostage deal, but will ultimately agree. Rick thanks Lamson and offers him water.
Gabriel limps through the forest and is attacked by a walker. He knocks it down and raises a stone to kill it, but then notices a crucifix around its neck. He tearfully lowers the rock and hobbles away.
As Sasha guards Lamson, he describes seeing a former colleague-turned-walker melted into the asphalt outside. Sympathetic, Sasha offers to shoot the walker to end its misery.
Out on the road, Eugene finally awakens and Maggie rushes to his side. Glenn, Tara and Rosita return with fresh fish and water. Tara has found a yo-yo.
Back at the warehouse, Lamson directs Sasha to a window and tells her where to aim her gun. As she's staring through the scope, Lamson slams Sasha's head into the window. With Sasha now on the ground, bleeding and unconscious, Lamson makes his escape.
