Naked and Afraid Brazil

Ten survivalists are thrown into the bleak Colombian savanna. Extreme heat and more dangers of nature threaten the teams with one pair struggling to make it to a water source and another being forced to sleep out in the elements.

The survivalists are left to wonder if the psychological challenges of surviving in the Colombian savanna are more difficult than the physical. Ji continues to struggle with her blisters, Tony is shaken by horrible nightmares and Sati clashes with Rene.

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.

Heavy storms put the survivalists' shelter-building talent and intense situational skills to the ultimate test. Érika and Itamar try to find more resources while Léti barely eats or sleeps due to the extreme cold. Raysa and Diogo's relationship is shaken.

Léti, Érika and Itamar face their most challenging moment without energy or harmony in the group. Gi and Joedson play their last cards before they run out of energy while Sati and Rene get a game-changing surprise.

After a challenging and dangerous hike, a great encounter surprises everyone and completely changes the dynamics of the challenge. Rene struggles to lead and feed her group while Sati suffers an accident that threatens his future in the competition.

Extremely weak, the participants get to the final stage of the challenge. The journey to the extraction point is long and plagued by difficulties -- how many survivalists will conquer the most extreme challenge of their lives?
