Wolfpack (1987)

High school student Sam Adams has just moved to a new house in a sleepy, all-American town. His new school seems perfect at first and he is quickly accepted onto the football team. But something about his fellow players seems a bit off, particularly the brutish and arrogant Jack "Boot" Butkowski. As Sam soon discovers, the team have appointed themselves as dictatorial leaders of the school, openly modeling their behaviors after the SS and terrorizing anyone who doesn't fall in line, while rewarding those who pledge blind allegiance. When Sam's unwillingness to submit results in a violent attack on an elderly family friend, he decides to take matters into his own hands...
