Teenager John Heidelberg works at a comic book store, lives with his grandmother Ruth, and occasionally receives reprimands from his elders for not following Torah. One day, as John returns home, he witnesses a masked stranger killing a close relative. Afterwards, a man named Meyer Offerman tells him that there is a high probability that the perpetrator was a Nazi. He introduces John to a group called the "Hunters," who are fighting against surviving followers of Nazism after World War II.
