Steve Backshall and his long-suffering crew return for more deadly encounters with animals hoping to earn a place on his hallowed Deadly 60 list. Steve and the crew are thrown deep in the steamy rainforests of Costa Rica. They are on a mission to find the largest cat in South America - the awesome jaguar. But the jungle is teeming with wildlife - from venomous snakes to squealing frogs - so there is plenty to see along the way. Even after dark the forest is alive with deadly creatures, and down by the river Steve has a battle with a giant, reptilian predator.
