An eccentric inventor has thought of a way that automobiles can run on radio waves, without gasoline. His plans put him in conflict with the owner of an oil company, who is also pursuing the inventor's daughter. This rival begins to scheme against the inventor, and it is left up to the inventor's hired man to try to stop him.
All the qualified men line up to be chosen, as an heiress advertises that she will marry the man with the most interesting mustache, that marriage which comes with a mansion. John Syrup Soother wins the marriage to who he believes is the heiress, Olive Palmer, a tank of a woman who has lost her beauty with age. But he learns that he his betrothed is not the heiress, Diana Palmer, but her mother. Howson Lotts, a shyster and one of Diana's other suitors, sells John a beach-front house for his new life, that house which is not all that it seems on the surface. In the meantime, others still will do anything to be Diana's betrothed, that choice in which John now has a different but still vested interest.
