Joey and her brother Gray, a rafting instructor, go on a rafting expedition down the Kootenai River along with their best friends Vanessa and Karissa and Gray’s friend Trevor. During the expedition, Vanessa is wounded and claims that Trevor attacked her. All the phones don’t work and they decide to go down the river to find help. Trevor wants to cross the border and escape, but Gray manages to convince him to let them live because he can’t cross the river and the rapids without them. They approach the rapids and waterfall and Gray instructs Joey on how to get down. The rapids throw them out of the boat, but a helicopter comes to the rescue and takes them to safety.
