Thirteen contestants go abroad the X-bus and are taken to a series of locations around the globe that are unknown to them. Throughout each episode, they will try to gather clues to try and guess where they are and if they are confident enough on where they are, they place their "X" on the map. If they're close enough to the actual location, they go through to the next episode, but if they're the furthest away, they are eliminated from the game. The series winner will win £100,000.
