Episode 5 - S1.E5

It is the climax of the expedition as the team prepares to explore a 100-metre chasm at the very bottom of the Amazon river. Scientists have no idea what lurks within. At first, underwater robots take cameras down the abyss and find the deep water flesh feeding Candiru-açu. Then, as the expedition draws to a close, the team of divers led by Mike deGruy prepare to jump into the depths of the river to confront and film the extraordinary fish that lie in the depths.
