The detective trio are depressed over a lull in business, when Murray's attractive, practical joke-loving sister Melba arrives, looking for their help in proving her theory that Hitler had established a port on the U.S. west coast during World War II. She neeeds to prove the theory after her initial report was rejected by a publisher and editor. With the help of a German historian friend of Melba's, they begin their search for a German U-boat loaded with gold that was rumoured to have sunk somewhere in the area, but their party comes under attack from the publisher and editor who rejected Melba's report, who want to get their hands on the sunken gold for themselves. But unbeknown to the detectives, the pair aren't the only ones out to sabotage the quest...
