In exchange for a sum of money, taxi driver Tarek Fahd agrees to spend 14 days undergoing a psychological experiment aimed at studying the dynamics between guards and prisoners, held in a fake prison. A former journalist, he decides to make a documentary film based on this experiment, using a tiny camera hidden in the frame of his glasses. Just before the two weeks begins, Tarek meets Dora, who is suicidal, and spends the night with her. The following day, the experiment starts, with the 20 male candidates divided into eight guards and 12 prisoners. Tarek, who is chosen to be a prisoner, decides to spice up his report by provoking the guards, who are not allowed to resort to violence. But while hounding a touchy guard named Berus, Tarek’s actions cause the experiment to spin dangerously out of control.
