12 celebrities arrive in the Costa Rican jungle. Their first mission is simply to reach the lodge — without Bear Grylls getting to them first.

Four people are still in the Bear Pit, and one is not coming back. As they try to dig, climb and race their way to freedom, Bear is not far behind.

A new challenge sees four celebs thrown in at the deep end. When one finds himself in over his head, his teammate fights to finish the task on his own.

As the second celebrity is eliminated, the pressure — and tension — is rising within the camp. Some find themselves wobbling over the next challenge.
