The story of a rich man who, bored with life, goes to see the seamy side in a cheap boarding house, where he finds love and happiness. The sentiment is constantly offset by shrewd satire and comedy, the best of which is given the young pair of amateur detectives. Both live in Mrs. Prouty's house. Shorty is a movie "stipe" who hopes some day to play Sherlock Holmes, and Gladys, the landlady's daughter, has her own idea of scenting suspicion. When the mysterious "Mr. Prince" comes to board with the Proutys, Shorty and Gladys find adventure in their avocation.
