Nine people are dropped in Venezuela’s vast wilderness with one goal: find civilization. After sleeping on Mt. Roraima, they trek into the jungle where they battle hunger, fatigue and weather. By day three, hypothermia could force the first to leave.
The group grows desperate when they find themselves lost in the jungle at night with no water. Michael proves his worth by tracking a deadly South American snake while Brad and Sam are attacked by the very animal they’re trying to trap on a hunting trip.
The harsh reality of the Venezuelan backcountry forces the first person to quit. The team gets to their new camp but they find themselves without shelter when a severe storm rolls in. Later, Nick and Michael make a meal out of termites.
The group takes shelter in a Pemon Indian hut and Brad goes hunting with handmade arrows. Sam and Michael still can't see eye to eye and the group isn't happy. The journey may come to an end for two more people.
Six people remain on the journey. The hungry team catches a break and hauls in their biggest catch yet but it's not enough to keep another person from quitting. Also, Sam reveals an embarrassing medical issue to the rest of the group.
Five people remain on the quest to make it out of the wild. Nick and Brad become stranded by a flash flood, Ryan contemplates pushing the button and Brad gets a message from home.
The remaining group struggles to build a raft sturdy enough to carry them down river. They celebrate their largest kill and biggest meal of the journey but the joy is short lived and emotions run high as the desperate search for food continues.
Life on the river proves more difficult than anyone imagined. The physical exertion and lack of food causes one member to collapse while the rest of the team must rally to search for any sign of civilization.
