"What Would You Do For A Million Bucks?"

When an elderly millionaire has a heart attack while watching a sexy striptease, his wild will leaves everyone in a state of salacious surprise. It seems that he decided to leave his fortune to whichever couple can prove themselves to be even more sex-crazed than he was! His probate lawyer gathers together three loving couples for a weekend of utter debauchery, watching them on video monitors as they try and prove themselves filthy enough to qualify for the cash. Things take a strange and sordid twist when someone starts trying to bump off the carnal competitors!
