The Black Whale III embarks on an eerie voyage into the mysterious Bermuda Triangle, carrying the Marvin family on a quest to uncover the legendary remains of Atlantis. As the ship cuts through the seemingly endless ocean, the crew’s journey quickly takes a strange turn when they discover a mysterious doll floating in the water. The youngest member of the family, Diana Marvin ([played by a young actress]), becomes inexplicably drawn to the doll, which appears to exert a sinister influence over her.
Soon after, Diana begins to exhibit unsettling behaviors, warning that everyone on board will die. She even predicts the order in which they will perish, creating a pervasive sense of dread among the crew. Her disturbing actions escalate when she locks the ship’s cook in the freezer, narrowly avoiding a tragedy when he almost succumbs to the cold before his rescue. The tension on the boat intensifies overnight when, despite no visual signs on their radar, the ship responds to an SOS signal that turns out to be from a vessel lost years earlier, forcing the crew to abandon their search.
Upon reaching their destination, the crew gears up for a daring scuba dive to explore underwater ruins believed to be linked to Atlantis. During their exploration, a sudden underwater earthquake causes chaos, tragically crushing Michelle Marvin’s (the eldest daughter) legs, leaving her severely injured. The crew's attempts to seek help lead them to the nearby island of Bimini, but their efforts are thwarted when a fierce storm hits, damaging their engines and steering mechanisms after they hit rocks.
As the storm rages on, tragedy continues to strike: the ship’s cook dies in what appears to be an accident, and Diana’s parents are swept overboard during a frantic search for her. The following day, an attempt by the ship’s engineer to repair the damaged helm ends in further loss, when Michelle’s brother and the ship’s mate leave in a motorboat to reach Bimini, only for their vessel to become lost at sea. Sadly, Michelle, in her vulnerable state, succumbs during the perilous voyage. The boat carrying her and her rescuers vanishes without a trace, just as Diana’s Aunt and Uncle are killed in mysterious circumstances, seemingly under the influence of the doll.
Back aboard the Black Whale III, the captain tries desperately to send distress signals, which are eerily echoed by other ships in the area. Amidst the chaos, they finally manage to contact Bimini, only to encounter a skeptical radar operator who reveals that the Black Whale III had been reported missing twelve years ago with the Marvin family aboard. As the ship slowly disappears into the ominous depths of the Bermuda Triangle, the sinister doll is left floating in the water, symbolizing the eerie and unresolved mystery that lingers beyond the lost voyage.
