A mother and her two young children rent a battered old RV (optimistically christened the 'Chateau') and embark upon a journey through the Alaskan wilderness. At first their trip feels like a vacation: they spot wild animals and build bonfires. But as they travel deeper into the forest, dodging wildfires and eccentric locals, we learn more of the events that forced them to escape their old lives in search of something redemptive, out at the very edge of civilization.
