The Wave movie plot

On the campus of a middle school in a small German town, a history teacher asked a question during a lecture on dictatorship: Is dictatorship possible in contemporary society? The students scoffed at this. Next, the teacher and the students in their class did an experiment to simulate dictatorship. He named the class organization "Die Welle" and guided the students to set up a unified slogan, a consistent way of greeting, and wear the same Style of clothing. After just three days, the students in this class have established a high degree of identification with their own organization. They are united, excited, and radical. All students who disagree are regarded as aliens. In a group fight with other classes, the history teacher realized the seriousness of the situation and summoned the whole class to the auditorium to announce the end of the experiment and the dissolution of the organization. However, it was too late. An avid student suffered a mental breakdown due to the disillusionment of his "faith". He shot and wounded a classmate before committing suicide   .
