The show starts with Rick, Daryl, T-Dog, and Carl entering a house looking for supplies. After clearing out a few walkers, they only find a couple cans of dog food. Carl starts to open it when Rick grabs the can, looks at it and throws it against the wall. Just then T-Dog looks at the window and sees a group of walkers heading towards the house. The group grabs a couple of blankets and weapons and flees to there cars.
Once they get inside, Rick finds a dead prison guard and takes his keys. After clearing out the C block, they get the rest of the group and they start to chose bunks. Lori tells Rick "Thank you", but Rick gives her the cold shoulder. Lori then bunks up with Carol as Rick starts patrolling around.
Back at the prison Lori pulls Hershel aside and tells him that she thinks the baby is dead. Worried that if the baby is dead, and everyone is infected, she is worried that the baby will turn and rip her up from the inside. She then goes on to say if she dies during the birth that she could turn and try to kill the baby. Hershel then tell her that everything is going to be fine. Lori, sobbing, makes Hershel promise if she or the baby dies or turns that he will kill them with out a second thought.
After Hershel's talk with Lori, he rejoins Rick, T-dog, Glen, Maggie, and Daryl who are putting on some riot gear that Rick found. They all start to move to the next part of the prison. They turn the corner and find a bunch of walkers. As they turn and run to flee the on coming horde, Glen and Maggie get separated from the rest of the group. They duck into a hallway to get away. The rest of the group goes back to look for them when Hershel walks past a corpse that jumps up and is not dead, but a walker. The walker bites Hershel on his calf right as Glen and Maggie come around the corner. They kill the walker and pick up Hershel to keep on fleeing.
They found there way into the mess hall and lock the door behind them. Rick ties his belt around Hershel's thigh. Rick says "There is only one way to keep him alive" and chops off Hershel's lower part of his leg, right about the bite. As T-dog is at the door making sure the walkers don't get in, the rest of the group hears a noise. Daryl aims his crossbow towards some figures in prison cloths behind a metal grate. They realize that they are not walkers but humans. As the episode came to an end, one of the prisoners say "Oh my God" and the show ends.
Its great to have The Walking Dead back. This episode started off kinda slow, but picked up between the middle to the end. I can't wait to see how long it will be before Andrea and Michonne meet back up with the group. Also if by cutting off Hershel's lower leg, if it will stop him from turning. The question also must be asked, how will the prisoners and Ricks group mesh together, and will they trust a former cop?
