Andi (Brigitte Bako) joins her husband Tim (Chris Sarandon) on a tropical island to help him with the dangerous task of capturing poisonous sea snakes for their venom. Andi's flagrant sensuality attracts the attention of hired hand Dak (Richard Tyson), and when Tim becomes bitterly obsessed with his faltering job, the muscled brute uses the opportunity to seduce the confused girl. When she realizes her mistake and refuses to give in to any more of Dak's advances, he becomes jealously violent and sabotages Tim's boat sending the diver to the hospital. With Tim out of the way, no one can protect Andi from Dak's barbaric lust...except Andi herself.
