In the not too distant future, Kabel (Gerard Butler), a death row inmate, has unwittingly become a pop culture hero. Every week, millions worldwide tune in online to watch him and hundreds of other convicts battle in Slayers, an ultra-violent multi-player online game invented by technological genius Ken Castle (Michael C. Hall). To the wealthy young gamer who controls his every move, Kable is just a sim (simulation) character. To the resistance group that opposes Castle's games as high-tech slavery, he is a critical element in their battle to take down the inventor. Caught in the crosshairs of two opposing forces and under the command of a teenager's remote device, Kable must use his extraordinary fighting skills to escape the game, bring down Castle and overthrow the system.
