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.

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

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

One survivalist scores the biggest hunt of the challenge. Chaco's coldest night yet leaves participants on the verge of hypothermia.

Each pair meets to walk in search of water and a place to spend the first night, protected from predators and the cold of the Argentine Chaco.
