An uptight Wall Street yuppie, Gordon (Mark Linn-Baker), and his dour attorney fiancée, Sydney (Lisa Hartman), find themselves marooned on a tropical island in the midst of their exotic vacation. They seem destined for disaster until they run into Bill (Gregory Harrison), a former New York stockbroker, now living in paradise, who rescues Lisa from her vacation gone wrong, not to mention her fiancé--just as Gordon meets the luscious Tarita (Charlotte Lewis), a lovely native who shows him around her beguiling home. Hijinks ensue as the straight laced twosome finds out how much fun--and how funny--a friendship of four can be. Tarita inspires the uptight Gordon to loosen up while Bill reconsiders a more profitable career to support his new girlfriend in this hilarious case of mate-swapping mayhem.
