The Bermuda Triangle stretches across roughly 450,000 square miles of ocean between Miami, Bermuda, and Puerto Rico, an area also known as the Devil's Triangle or the Vile Vortices, though its exact boundaries are still argued over. This episode of the Naked Science series lays out the region's reputation for swallowing ships and planes without a trace, some vessels never found, others turning up abandoned or wrecked on the seafloor. Scientists and researchers appear on camera to weigh the case history against the legend, checking specific disappearances against weather patterns, shipping records, and known hazards rather than treating every loss as unexplainable. The film also tracks how the Triangle got folded into wider paranormal territory, linked at various points to UFO sightings and alien abduction claims, and asks how much of that reputation comes from real incidents versus decades of retelling. It moves between disappearance accounts and the expert pushback on them, aiming to separate what the record actually supports from what the myth has added on top.
