Storyline:The young Israeli adventurer Yossi Ghinsberg (Daniel Radcliffe) is traveling in 1981 in Latin America. In Bolivia, he and his two friends Marcus Stamm (Joel Jackson) and Kevin Gale (Alex Russell) get to know the Austrian dropout Karl Ruprechter (Thomas Kretschmann). He claims to know well the unexplored areas in the Amazon and so the troupe breaks up to a hike in the jungle. But what starts out as an exciting venture soon becomes a nightmare. Yossi and his friends are simply abandoned by Karl and without any orientation they are stuck. Surrounded by the untouched and at the same time deadly nature, they have to find a way back to civilization ... Based on the memoirs of Yossi Ghinsberg.
