Devil’s Playground (2010)

In London, the company N-gen tests a performance booster on 30,000 people, only for disaster to follow. A month later, a fast-moving zombie plague grips the city, spreading through bites as the world begins to collapse. Cole, a hardened mercenary, has just 54 hours to track down the one woman believed to be immune, a chance at a cure that may also decide his own fate.
