Night is approaching and the survivalists need fire, water and shelter. Tensions are rising. Will everyone be able to hold out until the 30th?

One tribe suffers a near-fatal accident, another loses its hunting item, while a third receives a stroke of luck. Differences breed divisions.

A heat wave hits the tribes. And the lack of food forces the survivalists to take even greater risks to continue the challenge.

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

The competitors begin feeling the effects of malnourishment after four days in the savanna; Tony's mental exhaustion sets in and a lack of food leaves Joedson feeling weak; two competitors make a drastic decision about their future in the challenge.

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.
