Masquerade (1988)

Money can buy almost anything, except a way to know whether someone truly loves you. Bob Swaim's steamy thriller "Masquerade" stars Meg Tilly as Olivia Lawrence, a young heiress who seems to have it all: beauty, good breeding and a fortune worth $200 million. But behind the calm surface of her seaside estate in the Hamptons, something is missing - passion. Enter Tim Whalan (Rob Lowe), a handsome yacht captain and charming playboy who has no qualms about sleeping with his boss' restless wife (Kim Cattrall) or climbing the social ladder for sport. When he sets his sights on Olivia, she falls under the spell of this seductive stranger, never suspecting that he has more than romance in mind. Doug Savant co-stars as a local cop and old friend who has his doubts about Olivia's new love, and John Glover plays her sleazy stepfather.
