AJ Odudu hosts as the gruelling reality competition returns for a supersized second series in a new tropical location, on the uninhabited islands of Ha Long Bay, Vietnam. There’s double the drama, and double the money up for grabs, as two teams go head-to-head to get their hands on a £200,000 jackpot. The 16 strangers must put aside their egos and differences to tackle the ultimate test of physical ability, mental skill and teamwork, as they race to build a bridge over 1,000 feet of water in just 12 days to reach the cash, which lies below a tower on an island between two beaches. But there’s a twist: only one person from the winning team can take home this huge prize. Adventurer and explorer Aldo Kane joins the competitors to oversee challenges that will test the teams’ nerves and ability. Along the way, the teams face surprise dilemmas and devious temptations, as we discover who is prepared to deceive their teammates for personal gain. Working together is key, but in this pressure-cooker environment, everyone must decide who to trust and, most importantly, who is worthy of the £200k. In this first episode, 16 strangers from the UK have flown halfway across the world and signed up for an unknown challenge on one of Ha Long Bay’s 1,600 uninhabited islands in Vietnam. Separated into two teams of eight, and unaware of each other’s existence, both learn of the challenge facing them: building a 1000-foot bridge across the South China Sea to a central island, in just 12 days, to try to win £200k. As the teams get to know each other and attempt to start the build, they must first locate all the materials they need to build a bridge that will float. After just 48 hours on the islands, two volunteers from each team must decide which of them really has the hunger to win. They must decide between themselves who will be team leader and who won’t return to camp. Host AJ Odudu and former Royal Marines Commando Aldo Kane are with the teams every step of the way, as they endure basic rations, no hot showers and back-breaking challenges.
