Librarian Judy Ross becomes apprehensive when her father, Professor J. Bramwell Ross, a confidence man, is released from prison and comes to live with her in Knoxton. Judy has told the local people, including her fiancé Jimmy Duncan, that her father has been exploring South America. Consequently, civic leaders turn out to welcome Ross and request that he lecture about his travels. The golden opportunity is too much for the professor to pass up, especially when he learns that Jimmy wants to start his own toy factory in competition with the big one owned by his boss, Ethelreda Knox, who has refused to manufacture the toy electric train that Jimmy has invented. To raise money for Jimmy's train, the professor ends his lecture by giving the locals a sales talk about a valuable iridium mine he has discovered in South America. When his old accomplice, Petey, arrives in Knoxton, followed by the Duchess and Jack, two crooks demanding the money owed them by the professor, Ross enlists them all in a scheme to fleece Ethelreda and the others. Posing as the representative of a group of South American investors, Jack deposits his latest illicit haul in the bank and then bids up the price of iridium stock. The professor outwits them all by suggesting a partnership and accepts both offers. Following the professor's instructions, Petey poses as a blackmailer and extorts three thousand dollars from Jack and the Duchess so that the professor can pay for Jimmy's machinery. The professor then convinces the pair that Petey has been arrested and they decide to skip town before he talks. After drawing the money out of the bank, the professor has his pal McClusky impersonate a policeman and in the ensuing scuffle, he switches the suitcases and, as a result, Jack and the Duchess leave town with a case stuffed with paper. The professor then turns the money over to Jimmy and Ethelreda and promotes a merger between them. All ends happily as the professor marries Ethelreda in a double ceremony with Jimmy and Judy.
