The Tenth Level

The Tenth Level is a 1976 TVmovie starring William Shatner. Inspired by the Stanley Milgram obedience research, this TV movie chronicles a psychology professors study to determine why people, such as the Nazis, were willing to just follow orders and do horrible things to others. Professor Stephen Turner Shatner leads students to believe that they are applying increasingly painful electric shocks to other subjects when they fail to perform a task correctly, and is alarmed to see how much pain the students can be convinced to inflict in the name of science.
