In this episode, Rick discovers that the prisoner he left to be eaten by walkers has opened up the gates to the prison, allowing more herds to converge upon them. While trying to secure the perimeter, one of the group suffers a fatal bite. Meanwhile, Lori goes into labor and Maggie and Carl must find a safe room for her to deliver the baby. In Woodbury, Merle has reason to believe that his brother Daryl is still a live, but the Governor will not allow up to take a scouting party to check it out.
