A mad doctor runs a sanitarium in the desert, where his hunchbacked servant whips women who are chained in the basement and cuts the legs off bodies so they'll fit in the caskets. Complications ensue.

While serving in Vietnam, a demolitionist witnesses the brutal torture/rape/murder of a young woman...ultimately, he becomes a serial rapist and killer himself, preferring explosives as his murder weapon of choice.
