New Yorker Ray and Ugur from Holland are both terrified of water after suffering major trauma in their lives. Bear takes them to face their fears on a journey through fast-flowing jungle waterways in Southern Mexico. Ray, 60, lost his son, Marc, in a tragic accident in a swimming pool. It had been Marc’s dream to join the Navy Seals, but he drowned aged just 17, leaving Ray haunted by images of his son dying underwater. Ugur, 37, was in Thailand when the Asian tsunami hit – and he’s avoided water ever since. Can Bear take these two proud men and force them to overcome their fears by taking on some of the world’s deepest canyons and highest waterfalls? It’s going to be an emotional journey.
