A group of survivors must cross the country with a possible cure for the zombie apocalypse. The holder of the cure, a zombie-human hybrid named Murphy, may not be so cooperative.
Two years later, and the survivors must deal with new types of zombies and a mysterious threat known as Black Rainbow.
Catch Up On Past Seasons
Three years after the zombie apocalypse has ravaged the planet, a ragtag group of survivors join together to escort a man whose blood may hold the key to the cure to a CDC lab in California.
The team continues their journey to the elusive CDC lab in California, dealing with bizarre enemies both old and new and an increasingly insufferable -- and perhaps dangerous -- Murphy.
A new adventure lurks for Citizen Z, while our survivors face a totally foreign threat. Oh, and Murphy is causing all kinds of trouble (are you surprised)?
