Tropic of Cancer

Married couple Grace and Fred arrive in Haiti to heal their broken marriage. But complications arise when they connect with Fred's friend, Dr. Williams, who's created an in-demand new formula that sounds an awful lot like a forerunner to Viagra. Soon bodies start piling up on the island, and Grace finds herself succumbing to the lure of native flesh around her. As Grace becomes enamoured of the island's raw sensuality, her husband's real motivation for visiting the island becomes clear. Who will wind up in bed with whom, and how high will the body count go in between Grace's erotic acid trips?
