We begin with a flashback to before the zombie apocalypse, with Laurie confiding to a friend that she's not sure she loves Rick anymore, and being interrupted when Shane comes up to tell her that Rick has been shot. Cut to now, with Rick running across a field, Carl in his arms, Shane and a fat guy, Otis, the hunter who accidentally shot Carl, following behind. At the farmhouse where Otis lives, the patriarch, Herschel, takes charge immediately, hooking Carl up to an IV, arranging for Rick to provide blood for a transfusion (he and Carl are both A+). From Herschel's examination, the bullet has broken into fragments which will need to be removed.
The remainder of the search party is still making their way back to the RV, while at the RV, Dale checks T-Dog's arm and sees that he's got a bad infection. They search the nearby vehicles again, hoping for some antibiotics they might have missed before.
Herschel manages to remove one of the bullet fragments from Carl's belly, but the boy is shrieking and crying from the pain. Finally he passes out. Herschel says that the other fragments are in even deeper, plus it looks like there's some internal bleeding, so they need to anesthetize Carl, and put him on a respirator, and open him up. They'll need additional equipment and supplies for that. There's a high school about five miles away that had a FEMA shelter set up there - they should have the supplies, but last time they looked, it was overrun with zombies. Rick wants to go but Shane says no, he needs to stay here with his son. Shane and Otis volunteer to go and Herschel gives them a list. One of Herschel's daughters says she'll go find Laurie and bring her back to the farmhouse.
The infection has caused a high fever and T-Dog starts to rant, paranoid, alarming Dale. As the rest of the group nears the highway, a zombie attacks Andrea as she wanders away from the group. Before it can munch on her, Herschel's daughter rides up on a horse, bludgeons the zombie with a baseball bat and tells Laurie that she needs to come with her to Carl. Darryl thinks that's a bad idea since they don't know this girl, but she shouts directions to the farmhouse over her shoulder as she rides off with Laurie. When the group reaches the RV, it is decided that Dale, Darryl and Andrea will wait overnight at the RV in case little Sophia shows up, and make a sign for her telling her how to get to the farmhouse, while the rest of them will go now to the farmhouse. When he hears about T-Dog's blood infection, Darryl pulls a baggie of medicine out of his motorcycle saddlebags - Merle's stash, which includes crystal meth, painkillers ... and penicillin. He hands over the antibiotics to Dale at once.
As they wait at the farmhouse, Rick and Herschel talk. Herschel is hopeful about the future and finding a cure but Rick is pretty despondent. When Laurie gets there, Rick takes her in to see their son. A little later, she questions Herschel about how many times he's done this surgery and it comes out that he's a veterinarian, not a people doctor. She is not happy about that: "Aren't you over your head?" Herschel, calmly: "Ma'am, aren't we all?"
When Shane and Otis get to the high school, it is indeed overrun with zombies. They wait until nightfall and then distract the walkers with flares found in an abandoned police car. They get inside the FEMA trailer and collect everything on Herschel's list but they've taken too long and when they exit the trailer, the zombies see them. After quite a bit of running around, fat Otis amazingly able to keep up with the fit Shane, they take refuge inside the high school, barricading themselves behind a metal gate. The innumerable zombies growl and moan and reach for them through the gate (wouldn't you move out of their line of sight in hopes that they'd forget about you if they couldn't see you, instead of standing there in full view?) That gate isn't going to last long against all that dead weight.
