In the 19th century's final decade, chemist David Palmer returns to Oxford, Indiana, after living in Chicago for a few years.

Upon his arrival, David receives a warm welcome from his father, Dan, who makes a living breeding race horses.

The colt grows into a strong horse, ready to train for the racetrack with trainer Ben Lathrop.

Ben tells David that Dan Patch has made a record training run before he and his daughter leave.

Since the other drivers refuse to race, realizing their horse won't beat Dan Patch.

Because of trouble at David's regular work at the chemistry company, Ruth tells him to come home and solve it, not willing to risk her lifestyle.

When David comes back to Ruth, he tells her he has decided to sell the estate, quit his job and continue breeding horses instead.

David understands he is in love with young Cissy, and together they decide to sell Dan Patch for $60,000 to be able to live on the farm and continue breeding horses.
