Twelve prisoners and guards join together to form a new and just society but after only a few hours four of them launch a bid for power that shocks and appalls their fellow inmates.
A new prisoner arrives, a master set of keys is stolen, and the two most forceful prisoners come head-to-head in a showdown for leadership.
The prisoners start to pick off weak guards, the most powerful prisoner is sentenced to solitary confinement, and the guards rumble an attempted break-out.
The story of the infamous Stanford Prison Experiment, a psychological exercise designed to examine the nature of good and evil. In the summer of 1971, a group of American students volunteered to adopt the roles of prisoners and guards in a specially controlled environment - the experiment was terminated after less than a week when it became clear that the participants were being adversely affected.
The Experiment was a documentary series broadcast on BBC television in 2002 produced by Steve Reicher and Alex Haslam in which 15 men are randomly selected to be either "prisoner" or guard, contained in a simulated prison over an eight-day period. “The BBC Prison Study explores the social and psychological consequences of putting people in groups of unequal power. It examines when people accept inequality and when they challenge it”. The documentary presented the findings of what subsequently became known as The BBC Prison Study
