The Tenth Level plot
"A world of evil so terrifying no one dares penetrate its secret. Until now!"
A professor is obsessed with the fact that years ago people like the Nazis "just follow orders", which sometimes leads to terrible situations. He conducts a study among his students: if they do something wrong in their activities, another person will receive an electric shock. At least that's what the students think; in reality there will be no actual shocks, but the professor is only interested in how far the students are willing to go in the name of science.
