How do you cut through dense undergrowth from a wheelchair? How do you navigate a rainforest if you're blind? These are just some of the problems faced by eleven intrepid adventurers in their trek of a lifetime. Escorted by armed soldiers to protect them from bandits and drug traffickers, they have 28 days to cross 220 miles. From the treacherous Mosquito Coast in Nicaragua, they make their way through impenetrable jungle, crocodile infested rivers, and climb a live volcano to make it to their finish line - the Pacific Coast. From the Atlantic to the Pacific Ocean, this incredible journey takes these inspirational adventurers beyond their boundaries, and to their physical and mental limits.
