In the last hundred years, countless lives have been lost but nobody is really sure why. People have blamed everything from space aliens to sea monsters for the disappearances of ships and aircraft between Bermuda, Puerto Rico and Miami. But what's really going on? Is it some form of extreme weather? Could it be a rare ocean phenomenon? Or is something else at work? In Curiosity's The Devil's Triangle, a team of investigators go deep into the triangle to explore ocean floor wrecks and stage experiments to tackle the mystery once and for all.
