Masquerade (1988)

Young heiress Olivia Lawrence seems to have everything: good-breeding and a two-hundred-million-dollar fortune. But behind the serene façade of her East Hampton seaside estate, something is missing: passion. Enter Timothy Whalen, the young sailing instructor and playboy who isn't ashamed of sleeping with his boss' insatiable wife or social-climbing for sport. And when he sets his sights on Olivia, she falls under the spell of this handsome stranger, unaware that he has his eye on more than just her beauty--and his mind on something unimaginable. When the two run into a problem, the local policeman, who happens to be a childhood friend of Olivia's, seems to be turning a blind eye to incriminating evidence.—Rob Hartill
