Jocelyn and Alex have always been best friends...until they aren't. Jocelyn's not sure what happened, but she hopes the annual joint-family vacation in the isolated north woods will be the perfect spot to rekindle their friendship. But Alex still isn't herself when they get to the cabin. And Jocelyn reaches a breaking point during a rafting trip that goes horribly wrong. When the girls' tube tears it leaves them stranded and alone. And before they know it, the two are hopelessly lost.

Wearing swimsuits and water shoes and with only the contents of their wet backpack, the girls face threats from the elements. And as they spend days and nights lost in the wilderness, they'll have to overcome their fractured friendship to make it out of the woods alive.
