In this uncertain world, Rick Grimes (Andrew Lincoln) and his band of survivors must not only fight the dead, but also face a whole new fear: The living. In this 16 episode season, the series, Rick and his fellow survivors continue to seek refuge in a desolate and post-apocalyptic world and soon discover that there are greater forces to fear than just the walking dead. The struggle to survive has never been so perilous. This season also introduces new characters, including the Governor (David Morrissey) and fan-favorite Michonne (Danai Gurira), along with her zombie pets.
