Human Nature.

While his lonely wife yearns for his touch, disturbed husband Harry (Donny James Lucas) shuns her advances and throws his energy into his unusual hobby: abducting beautiful women and torturing them in his garage. This terrifying gore fest directed by Vince D'Amato is twisted enough -- until you find out it's based on real events. (Then, it's even creepier.) The supporting cast includes Cynthia Potvin, Dana McLoughlin and Tamara Pender.
