Devin, Nadia and Marcus are on their way to visit their environmentalist parents who are working to stop a logging company from clear-cutting a remote valley. When their plane crashes and the pilot is killed, the kids are left to survive in the wild with Wiley, a government bureaucrat, who is the only other passenger on the plane. Learning to build a shelter and make a fire in the woods, they discover that Wiley is working with the logging company and will do anything to stop the secret getting out.
