At St. Mary's College, a boarding school for girls located just outside Boston, Massachusetts, a lonely, gaunt, unattractive student, named Kathy (Milijana Zirojevic), becomes the center of a cruel practical joke perpetrated by a gang of students and the hunky, but sadistic gym teacher, Fred Vernon (Riccardo Acerbi). Kathy is tricked into going on a date with Mr. Vernon, but when she over eagerly makes her move onto him in his parked car in the woods, the students appear in their cars to taunt her. Running away from several carloads of her tormentors, Kathy runs onto a busy street where she immediately gets hit by an oncoming car and is admitted to the local hospital in a coma. Kathy's strange mother, Mary, continues to gloom around the school in her capacity as a cleaner.
