This movie takes place in Germany, which you’ll quickly realize is very ironic. Because it’s the story of a high school teacher who takes his class on an adventure in autocracy. In an attempt to give the students the feeling of what it’s like to experience a national movement like Nazi-ism, he starts enforcing strict rules, and eventually the students become so fascinated with the the experiment that they volunteer to wear uniforms and adopt a logo (a wave) that represents their “movement.”
However, as in real life, things don’t go according to plan, and a tragic event takes place. It reminded me of Lord of the Flies, and it ended just about as badly. But, I think you’ll find it fascinating. And it’s free on Netflix.
