Politiska och militära konspirationer mot en bakgrund av ett massivt zombieutbrott, där en småstadssheriff och irakveteran leder de överlevande bland ortsbefolkningen i jakten på en tillflyktsort.
Forest Peak, California. Fourth of July. Sheriff Danielle Adelman, a troubled war veteran, thinks she has all the problems she can handle in this all-American town after her kid sister runs away from home. But when a disease-stricken horde of panicked refugees fleeing the fall of Los Angeles swarms her small mountain community, Danny realizes her problems have only just begun - starting with what might very well be the end of the world. Danny thought she had seen humanity at its worst in war-torn Iraq, but nothing could prepare her for the remorseless struggle to survive in a dying world being overrun by the reanimated dead and men turned monster. Obsessed with finding her missing sister against all odds, Danny's epic and dangerous journey across the California desert will challenge her spirit... and bring her to the precipice of sanity itself...
