The guys’ adventure begins by zip lining across jungle canopy, rappelling down waterfalls and bungee jumping off a city bridge. They dive with sharks off the Galapagos Islands, and realize the human impact on animals there. On the mainland, they stumble upon the Intiraymi festival, where celebrations are contrasted by near-riots between conflicting tribes. Next, they venture into the Amazon to find the Hourani tribe, and arrive the day of the Chief’s father’s funeral. Attending the ceremony, they learn how the tribes are fighting to keep their traditions alive and protect their land.
