Marcus Bently is an alluring, suntanned, physically strapping young American man who who’s passion for sailing and diving inspired him to open a business leading undersea diving adventures with his best buddy, Dobs Towe. Marcus goes to the Dominican Republic because he falls in love with an heiress of a wealthy family, Catalina Arias, with whom he intends to marry – albeit with a slight case of cold feet. Catalina sets up a lavish bachelor party for Marcus and his friends aboard a luxury yacht, which ends up floating too close to an uncharted island. The island is a scientific research facility run by an inhumane Dr. Edwards, who is intent on finding a vaccine for a flesh-eating virus that could strip humanity literally down to the bones. Marcus and his friends must find a way to survive before the flesh eating disease consumes them all.
