Generate a question that has the following answer: Professor Klaus Thon for the following movie plot: While reading a newspaper advertisement, taxi driver Tarek Fahd discovers an invitation to participate in an experiment, in which 4000 German marks are offered to the participants of the experiment, in which a prison situation is simulated. The experiment is led by Professor Klaus Thon and his assistant, Dr. Jutta Grimm. He decides to join in. Tarek participates as a journalist while wearing a pair of glasses with a built-in mini-camera. Tarek has a car accident shortly before the experiment, after which he meets a woman called Dora. She spends the night with him and Tarek keeps thinking of her, shown in flashbacks. The 20 volunteers are pronounced guards and prisoners, 12 prisoners and 8 guards, and are being observed by a team of scientists. In the experiment, the prisoners lose their civil rights and have to obey arbitrary rules, such as completely eating their meals.

He befriends his cellmates, Steinhoff and Schutte. Psychological changes develop and the situation deteriorates. The circumstances seem to be escalating after a few days. It becomes clear that limits are not only being reached but being surpassed when the guards kidnap Tarek from his cell late in the night, order him to strip fully naked, shave his head bald and urinate on him. The guards become excessively aware of their power and use the prisoners' fear to make them obedient. On both sides, one person is considered dominant. On the prisoners' side, this is Tarek, and on the guards' side, it is the quiet guard Berus, a sadist, whose motto during the experiment is: "Humiliation is the only way we can solve these troubles." From that moment on, the guards start...
