An aeroplane goes down in the notorious Bermuda Triangle and on board is an Englishman recently heavily insured. The suspicious insurance company calls in Dan Felsen, former RAF pilot turned private investigator. Dan soon runs into trouble, which makes him suspect the infernal triangle is being used as a front for a much more sinister reason for the disappearance. His search for clues leads him to the Bahamas, the Caribbean and into a hurricane before he resolves the mystery.
