Over the course of ten days and 435 miles, an unbreakable bond is forged between pro adventure racer Michael Light and a scrappy street dog companion dubbed Arthur. As the team is pushed to their outer limits of endurance in the race, Arthur redefines what victory, loyalty and friendship truly mean.
