A group of friends decided to make a trek to the lost part of the Amazon jungle, but soon they would realize that jungle is a difficult place to be. Although there is no need to go into such dangerous places, the 4 friends did so. what I like more about the film is hope and the friendship between Daniel and Alex. Alex believed that his friend is still alive and tried his best to find him.
