Jungle:

What begins as a dream adventure for four amicable, if hastily met, muchileros (backpackers) quickly becomes a struggle for survival as they unravel under the duress of the jungle. They are an odd mix to be sure: Marcus, the Swiss mystic; Karl, the shady Austrian geologist; Kevin, the well-intentioned American photographer; and Yossi, the Israeli adventurer. Jungle is the incredible true story of Yossi Ghinsberg's triumph over the most adverse and frightening of circumstances. It is a tale of survival and human fortitude against the wildest backdrop on the planet.
