Tale of temptation. Reginald Wellingford is begged by his fiancee to give up his gambling and when he realises that he will be ruined if the horse he backed loses the next race and he would then have to renounce his engagement as a matter of honour, he thanks her as his guardian angel. A rival suitor bribes the formerly honest jockey to lose the race and thus ruin Reginald, but when Reginald saves the jockey's son from being run over by a train the jockey listens to his son- his guardian angel, and rides to win.
