: Jürgen Vogel is highly commended for his role as Rainer Wenger, an unorthodox teacher who begins to lose track of his own ego and conscience as his influence over his students grows.

Based on real events (the 1967 "Third Wave" experiment in California), the story follows a popular high school teacher who conducts an experiment during a project week on autocracy. What starts as a simple classroom exercise in discipline and unity quickly spirals out of control, evolving into a real movement that uses intimidation and violence against those who oppose it.
