Richard Hammond is on the mighty Amazon itself, leaving the main river to enter the flooded forest in tiny dug-out canoes. It soon becomes apparent that the inhabitants of the Amazon are not keen to play ball when Richard struggles to even see the creatures spotted by his guide Eduardo, let alone photograph them. However, hours of frustration are finally rewarded when Richard enjoys once-in-a-lifetime encounters with sloths and Pink River Dolphins.

This time Richard will be facing biting ants, overcoming a personal phobia when he comes face-to-face with giant spiders, and tries to conquer his fear of heights when he is hoisted high into the forest canopy.
