Newlyweds Brandon and Brandy Wiley are on a backpacking adventure in Costa Rica, when their 8 - person Cessna crashes in dense tropical rainforest. The pilots and one passenger are killed on impact. Of the five remaining survivors two are seriously injured, including American Michael Packard. With the plane's emergency beacon malfunctioning and the crash site obscured by thick cloud, the chances of rescue appear remote. When darkness falls, the group face poisonous spiders, swarming ants and jungle predators. By morning and with Michael's condition worsening by the hour Brandon and Brandy face a terrible dilemma - do they go in search of help or stay with the two injured men? It's a decision that could ultimately cost lives.
