Sixteen incredible adventurers, plucked from thousands, are stranded on a tropical island thousands of miles away from school, friends, family and normality. This is no ordinary island. It is a devious, mischievous, sinister place that will do anything it can to prevent the adventurers from escaping. The challenge is the Collision Course where the adventurers must swim upstream in freezing, fast flowing water, under submerged obstacles and into terrifying claustrophobic spaces. Which team will make it through to the Double Jeopardy round where the stakes are raised and the challenge is even tougher? Who will be taking on the Captain's Task? What else has the island got in store for the adventurers?
