A new group of contestants return to the Mina Dos Estrellas Mine, built in 1903 by European gold diggers, and said to have fallen prey to the wrath of the Nahual. The Nahual are creatures from Mesomerican legend, either witches or spirits that can change shape, taking on the forms of animals. Will any of the contestants make it through to the end, or will they all be driven away by their fears, as were the last group who attempted to stay there?
