German composer Valentin Reiner receives a letter from his ex-wife Anna, who now lives in Los Angeles with their 18-year-old son Stefan. In her letter, Anna asks Valentin to come help her with her child. Stefan is engaged to Leila, a young Muslim girl from Palestine, who is three months pregnant with her baby. They live with Anna and Judge Boccia, who hates black Muslims. Stefan and Leila hate Jews. Along with his friend Riff Mason, Stefan terrorizes the Jewish community with home invasions, where they paint swastikas on houses and leave fake anthrax letters. Reiner is determined to expose the fascist group and win back the trust of his son.
