An elite team investigates the mysteries of the Bermuda Triangle aided by a secret map decades in the making. In this episode, they attempt to unravel the mystery of why 27 US Navy aviators and crew vanished without a trace on the same night in 1945. While searching for the wrecks of the lost planes they uncover a debris field unlike any they have ever seen, and one with historic implications.

The team dives deep looking for the biggest vessel to ever vanish in the Bermuda Triangle–a massive ship with a monstrous name–the USS Cyclops. Was the USS Cyclops the victim of a terrifying, ship-sinking phenomenon known as a rogue wave? While searching the deep waters, they uncover harrowing stories of other rogue waves prowling the seas and make a discovery that solves a century old mystery.

The team searches for the remains of an entire pirate fleet of ships that vanished suddenly in the Bermuda Triangle, as if swallowed by the ocean. Could a geological anomaly be the source of these ship-sucking whirlpools? Their investigation takes them to the literal bottom of a fabled–and potentially deadly–mid-ocean sinkhole, but what they find waiting in the depths may prove beyond any mystery.

The team signs up one of the most advanced research ships on the planet to search the depths for a lost secret weapon of the Pentagon's arsenal--a top-secret spy plane that vanished into the Bermuda Triangle. Are planes and ships falling victim to a terrifying ocean storm called a white squall? The skies darken as the team pushes deep into dangerous waters attempting to identify whether the plane was lost to freak weather, or something even darker.
