New York City, 1976. Whenever mild-mannered Duane Lewis hears disco music, murderous and manic impulses are unleashed. After falling into a psychotic trance at a disco dance party, Duane escapes the city and reinvents himself as a teacher at an all-girls private school. Wearing special gear to cut out external sounds, he believes he's put the past behind him, until he's bombarded with decibels by his disco-loving students, transforming him into a funk-crazed serial killer.
