I heard the rustle again, too close and too real to ignore. I clutched the flashlight, stuck my head out of the mosquito net... and found myself face-to-face with a jaguar.

Four travelers meet in Bolivia and set off into the heart of the Amazon rainforest to find a hidden tribe and explore places tourists only dream of seeing. But what begins as the adventure of a lifetime quickly deteriorates into a dangerous nightmare.

After weeks of wandering in the dense undergrowth the group splits up after disagreements, and Yossi and his friend try to find their own way back without a guide. When a terrible rafting accident separates him from his partner, Yossi is forced to survive for weeks alone against one of the wildest backdrops on the planet. Stranded without a knife, map, or survival training, he must improvise shelter and forage for wild fruit to survive. As his feet begin to rot during raging storms, as he loses all sense of direction, and as he begins to lose all hope, he wonders whether he will make it out of the jungle alive.

The basis of an upcoming motion picture starring Daniel Radcliffe, "Jungle" is the incredible story of friendship and the teachings of nature, survival and human fortitude and a terrifying true account that you won't be able to put down.
