In a stunning display of determination and grit, a group of misfit cowboys from New Mexico find themselves catapulted onto the most unlikely journey when their undersized thoroughbred racehorse qualifies for the Kentucky Derby. Based on the true story of Mine That Bird, an underdog who defied impossible odds to win the 2009 Kentucky Derby in one of the biggest upsets in history, this film chronicles the team's quest to overcome every hurdle and become the ultimate underdogs in a final showdown with the racing elite.
