A sun-soaked true crime series that sees Captain Lee search for answers to some of the most remarkable, unsolved crimes ever to have taken place on the high seas. The captain sets sail for some of the world's most exotic locations, but he's not investigating small-scale vacation-gone-wrong crimes, he's looking into the craziest, most remarkable and downright bizarre crimes that have happened just off the coast of paradise. With on-location shooting, eyewitness testimony, shocking revelations and new evidence, this is one voyage no one will forget.

One victim, found dead on a London street. Four detectives, in four different time periods, must solve the mystery to protect Britain's future.
