Ten survival experts are abandoned naked in an inhospitable Colombian savannah. After going through the awkward moment of meeting without clothes, each couple begins their journey that should last 21 days.

Contestants face the African savanna, divided into tribes racing to secure fire, water and shelter before nightfall; the environment brings freezing nights and scorching heat, while predators hunt in the shadows.

In the first days of the challenge, the participants realize that nothing will come easy for them. The blisters on Gi's feet condition the good progress of the duo with Joedson; conflict between Sati and Rene breaks out.

Alana Barfield and Keith Busch attempt to survive on a Fijian island with minimal water and little food.

A heat wave hits the tribes, and the lack of food forces the survivalists to take even greater risks to stay in the challenge.
