In 1958, Erik Ponti, a 15-year-old boy, lives with his mother and sadistic stepfather in Stockholm. At home, his stepfather beats him every day after dinner. His docile mother ignores her husband's sadistic nature and allows the violence to proceed. At school, Erik is violent and frequently engages in fights, as a result of his violent upbringing. After a particularly vicious fight, Erik is expelled. The headmaster labels him vicious and accuses him of being pure evil. In an attempt to provide her son with a fresh start and last chance to finish school, his mother sells some of her valuable family heirlooms and sends Erik to an affluent boarding school.
