Join Steve Backshall on one of his best ever missions, this time to the heart of South America. A hunt for the mighty anaconda goes badly wrong when Steve is attacked by an unseen predator; when he does find his snake it almost breaks his hand. Steve takes a dip in piranha-infested waters to see these voracious predators up close, and has a surprising face-to-face encounter with the creature that bit him. Steve's mission then takes him over the border into Peru, where he meets the fierce giant river otter and another very different - but equally formidable - snake.
