In 1933 Berlin, Professor Nichols runs the American Colony School. It is next to the Horst Wessel School, where young Germans are indoctrinated into Nazism. During a brawl between the student bodies, Karl Bruner, a German youth born in the United States, objects when Anna Muller, a US citizen born in Germany, smacks him with her baseball bat. The students are attracted to each other despite this beginning. Anna's parents had sent her to Germany to be educated, although they allowed her to go to the American school. Soon, the professor, Anna, and Karl become good friends, though they do not agree politically. After a while though, they lose touch with each other.
