The Bermuda Triangle: Into Cursed Waters S01E03 - Holes in the Ocean

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-sinking 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.
