Flat broke upon their arrival in Peru, Rob and James land jobs teaching English in a Peruvian school. But in Cusco, the ancient Incan capital, tension between Rob and James builds to breaking point - resulting in Rob declaring that he wants to continue the journey alone. Reeling from Rob's bombshell, James decides to continue, and spends an emotional day clearing family graves on The Day of the Dead. Five hundred kilometres behind James, Rob sleeps rough and scavenges food from bins in order to survive.

Still travelling with no money, and relying on ingenuity and the kindness of strangers, Rob and James have only 12 days to cover the 1,250 miles to Panama. Along the way, they head deep into the heart of the Ecuadorian rainforest; work in exchange for shelter; and are forced to survive on insects foraged from the forest floor. Can they make it to their final destination without the aid of a credit card? And what will this epic journey have taught them?
