Ben Crane (Kurt Russell) is a horse trainer who is struggling to connect with his precocious daughter, Cale (Dakota Fanning). But then a horse by the name of Soñador suffers a broken leg after its evil owner (David Morse) races her despite Ben's advice. Rather than put his client's injured horse down, Ben adopts her and welcomes Cale into the family business. They train Soñador to race again as grouchy but kind-hearted Grandpa (Kris Kristofferson) lends his encouragement.
