In 1975, three children, Jimmy, Sean, and Dave, are playing on the streets of Boston when a stranger approaches them. Since the stranger has a badge and is wearing a suit, the children assume that he is a police officer. The stranger orders Dave to enter his car, and Dave obeys, but this leads to him being sexually abused and locked inside a basement for four days, after which he manages to escape.
