In the deadly wake of a viral outbreak, the human race is on the brink of extinction. Zombies walk the Earth and hunt the living. Among the chaos, lone wolf Nick discovers an old diary that contains a map indicating a sanctuary that might be his last chance at peace. Teaming up with another survivor, the reckless John, Nick journeys through the ruins of society in search of refuge — but they quickly realize that even in a dead world, the ominous threats that walk amongst the living are every bit as terrifying as those posed by the dead.
