Renchard is one of the last people alive in Los Angeles after a plague kills or mutates everyone else. His daily life is a struggle to outwit the city's roaming zombie hordes. Brianna, another survivor, contacts Renchard for help finding Antioch, a community rumored to have other survivors. He refuses, but then he changes his mind when two representatives from Antioch tell Renchard that Brianna's blood can cure the plague.
