During project week, high school teacher Rainer Wenger (Jürgen Vogel)
comes up with an experiment in order to explain to his students how
totalitarian governments work. A role-playing game with tragic results
begins. Within a few days, what began with harmless notions like
discipline and community builds into a real movement: THE WAVE. By the
third day, the students start ostracizing and threatening others.

When the conflict finally erupts into violence at an intramural water
polo game, the teacher decides to break off the experiment. But it's
too late. THE WAVE is out of control...
