Sweet, Sweet Freedom (1976)

Faced with patients who die before they pay their bills, the staff at Carcinoma Hospital has hit on a novel way to keep the patients alive - dispensing hourly boffings so they'll have a reason to fend off the Grim Reaper. Naturally the nubile young nursing corps plays a big part in the plan, and the gorgeous Marlene Willoughby leads the white-clad sexual shock troops into carnal combat. And then there's the incompetent Dr. Mort, played by adult cinema legend big John Holmes. He brings his formidable uh, medical knowledge to keep a string of appreciative female patients in the land of the living.
