A. Stranger, who registers from any old place, calls on I. Collier Downe, a Chicago millionaire to sell the famous volume "Success Secrets." They reach an agreement by which A. Stranger, furnished with funds by Downe, goes to New York to clean up a million in seven days. In New York, A. Stranger, posing as I. Collier Downe, meets Wright Innitt, a New York society leader, and his daughter Weigh Innitt. Posing as a hotel detective, he secures money from a guest, and speculates in Prune Juice stock, which is quoted at one cent a share. His spectacular adventures arouse the attention of the Metropolitan Press, and when it is discovered that the pseudo I. Collier Downe uses Prune Juice to bathe in, Prune Juice becomes the fashion in social circles. The former book agent capitalizes his notoriety, and Prune Juice stock rockets to $28.00 a share. The real wife of the real I. Collier Downe lives in the New York Hotel, where the false I. Collier Downe holds forth. She believes her real husband is there. In the meantime, the real I. Collier Downe reads in the newspapers of his impersonator's success and newly-found fortune in Gotham. He hurries to New York to cash in and expose the faker, so-called. He is refused entrance to the hotel, and the former book agent is instrumental in having I. Collier Downe incarcerated in a lunatic asylum. Then it is that the man who impersonates the real I. Collier Downe sells his stock for a million dollars and immediately thereafter there is a crash in Prune Juice stock, which breaks to a jitney per share. The real I. Collier Downe makes his escape from the asylum and rushes into the hotel, confronting A. Stranger and his friends. I. Collier Downe's wife spies her husband and there is a reconciliation. "We promised to split fifty-fifty on the money I made in New York, and here is half of the check," says A. Stranger, and I. Collier Downe and his impersonator divide the proceeds.
