 In the future, the walking dead are an every-day nuisance. An ex-police detective is hired to discover the cause of the undead "Infestation". His investigation leads him to a discredited scientist, and together they uncover a conspiracy that reaches far beyond the zombies. Teaming up with a pair of bickering exterminators, the heroes find themselves up against a multinational corporation who may just be behind the "Infestation" themselves.
