Wastrel son of a railroad magnate, Jack's father becomes frustrated with his son's wild ways. To prove himself, Jack goes to work in the railroad yard as a laborer. An escaped convict, Silent Bill Brachley, steals Jack's car, and the chase leads to a meeting between Jack, the engineer of the Midnight Express, and the engineer's pretty daughter, Mary. As he is led back to jail, Brachley swears revenge.
