Los Angeles County park ranger, Jack Carter, is about to discover that not all is as it seems in his tranquil life. Once responsible for patrolling the many public parks, in particular the popular Griffith Park with its famous observatory and zoo, Jack is about to discover that a whole new kind of animal roams his woods. The undead kind. Now, with his daughter bitten, it's a race against time to save her-and stop a madman hellbent on destroying everything that Jack has fought so hard to save. With time running out, and a doomsday clock ticking, Jack Carter will sacrifice everything to save the ones he loves...even while the walking dead multiply...and grow hungrier and hungrier.
