Satania(1986)

Satania is a adult film that reimagines the eternal battle between good and evil through a provocative wager. A demon named Satania bets a rival angel that she can corrupt a virtuous man into sexual excess within seven days. Armed with seduction and temptation, she sets out to prove that carnal desire trumps moral conviction. As Satania deploys her arsenal of physical allure and erotic encounters, the film explores whether the man's fundamental decency can withstand her relentless assault on his principles. The stakes of their supernatural bet hinge on whether genuine virtue can survive intense temptation, or if everyone has a breaking point.
