A very large number of walkers in the woods hear the noise caused by Carl's gun. They all start to walk in that direction. Rick and Carl run to the barn. Rick tells Carl to set the barn on fire after the walkers come inside. Rick and Carl leave the barn from an upper level while the walkers burn. With walkers all over the farm, a large battle takes place. Jimmy and Patricia are killed and Andrea is left behind. The rest drive away from the farm. Andrea runs into the woods. She is chased by many walkers. She kills many of them and is later rescued by a hooded woman. This woman, Michonne, is carrying a sword to kill walkers. She also has two walkers with her. These two walkers have had both of their arms and their lower jaws cut off. Michonne leads the armless walkers around with chains around their necks. The survivors all meet back on the highway where they lost Sophia. They drive off but must soon make camp when Rick's vehicle has no more fuel. Rick tells them that "this isn't a democracy any more" after he tells them what Dr. Jenner told him. Jenner told him that all of the survivors are infected. A large prison is shown in the be background as the episode ends.
