30 years after a nuclear apocalypse, a hardened survivor has managed to stay alive with his highly trained attack dogs by following one unbreakable rule: never let anyone through the gate. That rule has kept him alive for three decades. But when a desperate woman carrying an infant appears outside his sanctuary, Parish is forced to choose between compassion and survival. His decision exposes the refuge he has spent years building and puts him in the crosshairs of a vicious band of cannibals closing in from the wasteland. With his highly equipped compound under siege and his past finally catching up with him, Parish is forced into a brutal fight to protect everything he has left.
