Risky Business 1983

Left alone in the wealthy northern Chicago suburbs with the family house and Porsche at his disposal, Joel, through his scheming friends, finds himself entertaining to-die-for lady-of-the-night Lana. After meeting Joel's enthusiastic friends, Lana spots a business opportunity, and suggests bringing in some of her equally stunning colleagues. Joel is aghast at such an idea, at least until the Porsche accidentally falls into Lake Michigan, requiring a quick infusion of ready cash.
