A psychopathic mastermind (Gerard Butler of GAMER,300), captured for the murder of his wife's killers, threatens to unleash a gruesome killing spree across the city of Philadelphia unless he is released. The prosecuting attorney (Jamie Foxx of THE SOLOIST, THE KINGDOM) is usually a deal maker but this time stands his ground and refuses. As if on cue, innocent people start dying in horrifying ways - just as the prisoner warned.
