While plague zombies rage through the streets of London and begin their conquest beyond Britain, Jonathan, Holly, Cassie, and Garth try to stay alive. Vladimir Nesky seeks to complete his mission for Russia by apprehending Patient Zero before MI6's Director Sayers and her special forces team can steal him away to secure a cure for the virus for Britain. However, what no one realizes yet is that these ravenous zombies are changing, becoming lethargic and slow, desiring to feed more than infect so they can hybernate away in the dark, for they are becoming something else...something cunning and deadly that is no longer human.
