Joel Dommett welcomes 18 castaways to the Dominican Republic, to the ultimate physical and psychological competition show. Divided into two rival tribes, they live on remote beaches, build their own shelters, face the elements and battle against each other in epic challenges for reward or immunity. The two tribes are immediately pitted against each other in their first reward challenge - a brutally exhausting clash to retrieve basic supplies. Divisions begin to form, and personalities are put to the test as the losing tribe struggles to deal with the harsh environment. The groups also compete in their first immunity challenge, an intense feat of endurance. For the losing tribe, it means a sunset showdown at tribal council, where they must vote off one of their own. Which tribe will win the first immunity challenge? And who will become the first person voted out of the game, leaving their dreams of winning £100,000 and the title of Sole Survivor in tatters?
