Competitors from across the globe battle for national pride and $200,000; seven elite pairs from Australia, Brazil, Mexico and the USA enter the Olympics of Survival; over 40 days in Africa's Zululand, teams must survive apex predators, and each other.

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.

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

The cold sets in, hunger grows and risky hunts begin. Some grow weak, while others reap the rewards of persistence.

Conflicts erupt due to differences in personality or survival style. Unbalanced decision-making, tasks and workloads inflame tempers within tribes.
