The experiment works, and the couple secure a stunning wardrobe and a lavish room at a resort. Peter panics, however, when he gets a fantastic job offer.

Doctor Smith and his wife, Mary,depart a riverboat and are met by Phil Talbot. Phil informs Dr. Smith that Jessup, the only other white man in the village, has died while the doctor and his wife were off on a two-day holiday. Unknown to Smith, Jessup and his partner, Ross King, had a large cache of ivory tusks in the jungle, and he had told Phil about it. Meanwhile, Mary Smith has decided to steam-boat down the Congo River to Capetown for an extended holiday. Kuba, King's gun-bearer, asks Smith to write a letter to King, currently residing at a New York City Explorer's Club, and advise him that his partner has died. Talbot sends a letter to his stateside sweetheart, Diane Cameron, and her father, asking them to come to Africa and join him on an ivory-treasure expedition, and replenish their family-fortune lost in the recent stock-market crash. What Mr. Cameron and Diane don't know about Talbot is that his years in Africa have unhinged him...

In his last film assignment, portly Walter Connolly fills the title role (in more ways than one) in The Great Victor Herbert. Very little of Herbert's life story is incorporated in the screenplay (a closing title actually apologizes for the film's paucity of cold hard facts); instead, the writers allow the famed composer's works to speak for themselves. In the tradition of one of his own operettas, Herbert spends most of his time patching up the shaky marriage between tenor John Ramsey (Allan Jones) and Louise Hall (Mary Martin). Many of Herbert's most famous compositions are well in evidence, including "Ah! Sweet Mystery of Life", "March of the Toys" and "Kiss Me Again", the latter performed con brio by teenaged coloratura Susanna Foster. Evidently, the producers were able to secure the film rights for the Herbert songs, but not for the stage productions in which they appeared, which may explain such bizarre interpolations as having a song from Naughty Marietta.
