Eight celebrities embark on a 12-day expedition in the rainforest of Costa Rica, where they must learn to navigate difficult terrain, build shelters, make fire and eat the food that nature provides. From abseiling down ferocious waterfalls to crossing perilous rapids, the stars face a range of challenges and Bear himself eliminates one of them each week, leaving three in the final.

Running Wild with Bear Grylls, the survivalist takes one celebrity into the most remote locations in the U.S. and around the world for a 48-hour journey of a lifetime. From skydiving into the Catskill Mountains, to rappelling down the cliffs of Utah and battling torrential wind and rain in Scotland, Grylls and each celebrity will have to push both their minds and bodies to the limit to successfully complete their journey.
