Overview: Ashton Kutcher joins Bear to challenge the coastal jungles of Costa Rica. Their adventure begins with a helicopter jump into the Pacific Ocean. Once they swim ashore, they must canoe up a river to fish for their dinner, then descend a 300-foot cliff into the jungle. The next day, Bear sets up a commando crawl rope challenge. Ashton must use all the strength he can muster to cross a massive ravine.
