Bear Grylls pushes different celebrities to their limits in his show on ITV. Eight stars join the host and venture into a tropical forest in Central America. The heroes face a 12-day trek, during which they will fight for survival in the natural environment. At the end of each challenge, Bear Grylls chooses one celebrity to be eliminated from the game. Only three participants will make it to the final, competing for the title of "Survivor of the Mission."
