Mark Wahlberg portrays Mikael Lindnord in this true story based on Lindnord’s struggle to become a winning adventure racer and gain the respect of his racing peers. Going for one final shot, Lindnord and his team tackle a grueling five-day race in the Dominican Republic with very little preparation, but tons of experience. Along the way a wounded stray dog adopts the team. They name the dog Arthur. It’s a race to the finish…as well as to the vet to keep their hero dog alive.
