Expedition Unknown · Season 15

Gates' intrepid curiosity and passion for epic exploration lead him on a truth-seeking quest spanning five continents. Gates sets sail across the Mediterranean to unravel the mystery of ancient shipwrecks consumed by Greece's own Bermuda Triangle. In Turkey, he unlocks the secrets and symbols of the oldest manmade structures in the world at Göbekli Tepe. And deep in the Pacific, he embarks on a groundbreaking mission to rediscover the lost plane of an American hero from World War II.  Later this season, Gates embarks on a treacherous safari in the savannahs of Kenya to investigate the Ghost and the Darkness, the legendary man-eating lions who killed as many as 135 railroad workers in 1898. Then, it's on to the Wild West, where Gates will investigate the mysteries of renowned hunter and showman Buffalo Bill Cody, and the conspiracy surrounding the location of his final resting place. In the remote swamps of South Carolina, the search is on for the lost treasure of Anne Bonny, the notorious female pirate who escaped a death sentence before vanishing from history.
