Dad and Ben haven't been getting along recently and Dad hopes a road trip to rescue a border collie will help them reconnect. But Ben is on to Dad's plan and invites Ben's thuggish buddy, Theo. The family dog, Atticus, comes along too and the story is told by Ben and Atticus. When their truck breaks down, they commandeer an old school bus, along with its mechanic, Gus. Next, they pick up Mia, a waitress escaping a tense situation. Only sharp-eyed Atticus realizes that Theo is on the run—and someone is following them.
