Planning to fleece wealthy Henry Dodd, Blackie Blaisdell and his band of crooks convince the millionaire that they have located the deposed president of San Salvador, a country in which Dodd holds mining interests. Meanwhile, Harry, a secret service agent on Blackie's trail, learns of the scheme and falls in love with Dodd's daughter, Dorothy. Dodd objects to the courtship until Harry prevents Blackie and his pals from carrying out their scheme. Out of gratitude, Dodd approves of Harry and Dorothy's marriage. All goes well until their wedding night when, as a practical joke, Dorothy's girl friends lock her in Harry's folding bed and deliver it to Peter, her former suitor. Harry follows and in the ensuing chase, runs into Blackie who has escaped from jail. After Harry arrests the crook, Dorothy's practical joke is explained, and the lovers kiss and make up.
