While scuba diving off the Bermuda coast, a young couple discovers a sunken WWII ship with a valuable cargo of morphine. Eager to recover the treasure, they team up with an experienced underwater salvager, but their excitement is tempered by the discovery of a century-old shipwreck nearby. The ancient shipwreck holds a far more mysterious cargo: thousands of ampules of a rare and valuable substance. Their find attracts the attention of local criminals, who see the morphine as a lucrative opportunity and are willing to go to great lengths to claim it for themselves. The couple's discovery sets off a dangerous chain of events as they navigate the perilous waters of treasure hunting, unaware of the true danger that lies beneath the surface.

Complications arise when the young couple and their salvager partner find themselves entangled with a ruthless Haitian drug lord, determined to seize the morphine for his own illicit purposes. The trio's moral and ethical boundaries are tested as they are pulled deeper into a world of deception, betrayal, and escalating violence. Their quest for treasure becomes a fight for survival, pitting them against cutthroat adversaries and the treacherous ocean depths. Amidst this turmoil, the significance of the ancient ship's mysterious cargo becomes increasingly apparent, hinting at secrets far beyond their understanding. It's a race against time, adversaries, and the elements, as the line between friend and foe blurs in the pursuit of wealth, power, and history-hidden beneath the waves.
