Brazil: Treading Water (S02E04)

The Amazon is teeming with dangers, so the group rents a boat to navigate the treacherous waters of the rainforest. They encounter venomous insects, aggressive snakes, and indigenous people residing in handcrafted dwellings. After being caught in a fierce thunderstorm and getting stuck in a towering tree, they face off against menacing pink dolphins. Seeking refuge, they board a plane to the stunning island of Fernando de Noronha, where they dive into the ocean and witness nearly a thousand baby sea turtles hatching. The mood shifts as Justin and Gisele realize their time together is drawing to a close.
