A wonderful trip turns bad when their yacht gets hijacked by a gang of ruthless criminals then shipwrecked on a deserted island. As the girls struggle to hide from the sex-crazed fiends, tempers flare and betrayal waits in the wings. Can the girls escape with their chastity intact, or will they be even able to escape alive?
