Sam Blake (Martin Kemp) is running out of time. Living in the shadow of a botched mission that claimed an innocent victim, the disgraced special ops sniper is plunged into a world of darkness when his daughter is taken hostage by a sinister terrorist. Out of options and with no one to turn to, Blake is forced to carry out their evil bidding and must assassinate six seemingly random targets within six hours on the streets of London. As chaos reigns and the body count rises, the city's fragile political climate is threatened. If shattered, the consequences would be catastrophic. With his old unit closing in and his daughter at the mercy of a psychopath, every second counts.
