Prosperous Hank Armstrong (Russell Simpson) owns a stable, routinely winning races with prize horse Sloe Eyes. In 1895, his small Michigan town grows excited over the invention of the car, to Hank's disgust. Despite his prediction that the unsafe and expensive vehicles will never replace horses, automobiles still take over. His son, Bob (Charles Emmett Mack), embraces the new technology, causing a rift between them. While Bob prospers in Detroit, Hank is forced to sell his horses and property.
