Putting One Over

Traveling on a Pullman train are two strangers who, except for a difference in hair color, bear a striking resemblance to each other. Horace Barney, the heir to a fortune, is on his way to a mental sanitarium, accompanied by his unscrupulous guardian Maurice Claypool and Claypool's accomplices, Dr. Wallace and Thomas Farrel. Jack Trevor, an automobile salesman, is substituted for Barney when the train crashes and Barney is killed. When Trevor awakens from his unconscious state, he finds himself in a mansion and addressed as Barney. He falls in love with Helen Townsend, Barney's cousin who is next in line for the inheritance. Trevor realizes the fraud and sets out to save the estate for Helen. Claypool, who wants to marry Helen, tries to declare Trevor insane and commit him to an institution. A series of fights, chases, and misunderstandings ensue, but Trevor finally forces a confession from Claypool and wins both Helen and the fortune.
