Someone has been preying on Bayport’s “Bachelor Elite” and eccentric millionaire Cornelius Digby hires teenage sleuths Frank and Joe Hardy to guard a priceless art object that he fears will be stolen. Their girlfiends, Callie Shaw and Iola Morton, are beginning to wonder whether their relationships with the boys will ever get beyond the “friendship” stage, and their best chum, Chet, has begun sneaking out of the house after dark. What could it all mean? In the end, they crack the case and find out a few things about themselves in this hilarious musical parody (with a gay twist) of the venerable Hardy Boys mystery series.
