On a remote Caribbean island, seven challengers take on Mother Nature's most brutal obstacle course, each with their sights on being crowned the ultimate champion.
Six remaining contestants, each with a unique superhuman skill, take on the coastline as they traverse gigantic trees, treacherous cliffs and bodies of water.
The challengers must face the mountains of Dominica, scaling through steep terrain and dangerous natural obstacles.
The final four battle the canyons as their last test, with waterfalls, pitfalls, volcanic lakes, and a sprint to the top of Witch's Hat - the tallest peak in Dominica.
