Railroad engineer Bill Buckley narrowly averts injury to Esther Miller, the daughter of the president of the company, when she falls on the tracks in front of his speeding train. In receiving a reward from Mr. Miller, Bill becomes involved in the villainous schemes of Raymond McKim, Mr. Miller's personal secretary, who makes it appear that Mrs. Buckley has been unfaithful to Bill and attempts to force Esther to marry him (McKim). Bill's son, Johnny, interferes on Esther's behalf; McKim receives his just deserts; and all ends happily.
