Several years ago, Joy's sister died in a car accident. Now Joy feels obligated to fulfill her unfulfilled dreams. She goes on a journey along the legendary American Highway 66 and meets musician Dylan along the way. He stops and performs in the places where his father once played. Joy and Dylan continue their journey together, following the rule: if someone wants to go off the route, this can only be done with the consent of the other. This careless promise will dramatically change their lives and will echo a full ten years later.
