Mackenzie, a troubled but daring teenage girl, is sent by her struggling mother to live with her uncle in Juneau, Alaska. Although Uncle seems like a supportive caretaker and friend, the relationship turns and Mackenzie is forced to run. Trying to make her way back to Seattle alone to find her absent mother, Mackenzie only winds up deeper in the Alaskan interior. Lost and with no one else to turn to, she shadows a loner backpacker, Bartlett, an unlikely father figure with scars of his own. Together, they cross the wilderness and discover sanctuary in the last frontier.
