Vincent Moon (Ice-T) is a member of a crime syndicate that has just finished building a new prison. The day before it is to open, he brings together 100 people who have wronged the syndicate in various ways, provides them with weapons and ammunition, and gives them six hours to fight each other to the death. A $10 million cash prize is hidden in the prison, to be split by the last three survivors, but Moon's men will move in and kill everyone if more than three are still alive when time runs out. Anyone attempting to leave the grounds will be killed by snipers stationed around the perimeter.
