the walking dead season 3

After spending several months fleeing remnants of the herd, the survivors make a new home in a prison infested with walkers but find greater danger from the treachery of two rescued convicts. In the process of clearing the prison, Maggie Greene is forced to perform a fatal Caesarean section on Lori to save her baby, and Rick becomes withdrawn and hallucinates visions of Lori and others who died. Meanwhile, Andrea and Michonne - who rescued Andrea near Hershel's farm - are discovered by Merle Dixon and taken to the town of Woodbury, which is led by a man known as The Governor. Michonne is distrustful and escapes to the prison, where she meets Rick's group and guides them on a rescue mission following Glenn and Maggie's capture. There are casualties on both sides, and The Governor, disfigured by Michonne, declares the prison group terrorists and Merle a traitor.

Reunited with his brother, Daryl Dixon briefly leaves the group with Merle before deciding his place is at the prison. Rick returns to his hometown to gather weapons and ammunition, and reconsiders his morality when confronted by an unhinged Morgan. Andrea, romantically involved with The Governor, convinces him to negotiate a truce with Rick; secretly, The Governor plans an ambush, and Merle thwarts it at the cost of his life. Andrea flees Woodbury but is captured by The Governor, who locks her in a room with a walker and launches a full-scale attack on the seemingly-abandoned prison. His army is ambushed by Rick's group, and The Governor massacres his own people for refusing to fight. The Governor escapes, and Rick's group returns to Woodbury to take in the survivors but are too late to save Andrea.
