Ben Fogle leads a team of deserving heroes through the uncharted Peruvian jungle on the second leg of his epic South American adventure from the Equator to the Tropic of Capricorn.

With no maps to rely on, Ben and his team must chart a course through the unexplored tropical rainforest in a quest to reach sacred Incan inscriptions known as the Petroglyphs of Pusharo.

Ben announces a major re-route through uncharted territory in a desperate bid to make up for lost time, but an hour into their trek one of the fittest members of the team suddenly cracks with heat exhaustion.

The new route is more hostile than anything they have encountered so far, and the team is drenched by the relentless tropical downpours.

Desperate to reach camp before nightfall, the adventurers realise that teamwork is the only way to get through this challenge. Show less
