Sati Albuquerque

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

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.

René struggles to lead and feed his group. Sati has an accident.

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.

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; Sati and Rene get a game-changing surprise.

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.
