18 people, carefully selected from across the UK, are marooned in a tropical location where they are divided into two tribes, competing against each other in a range of physical and mental challenges for reward or immunity. One by one, players are voted out of their tribes at the iconic Tribal Council until the two tribes eventually merge and the game becomes a head-to-head battle. Ultimately only one person can triumph, winning the cash prize of £100,000 and the title of Sole Survivor.
