Young Jerry West has a few problems. His uncle Crispin is broke and employs a butler who isn't all he seems. His other uncle, Willoughby, is rich but won't hand over any of his inheritance. And to cap it all, although already engaged, Jerry has just fallen in love with the wonderful Jane Hunnicut, whom he's just met on jury service. But she's an heiress, and that's a problem too—because even if he can extricate himself from his grasping fianc├®e, Jerry can't be seen to be a gold digger.

Enter 'the Girl in Blue'—a Gainsborough miniature which someone has stolen from Uncle Willoughby. Jerry sets out on a mission to find her—and somehow, hilariously, everything comes right.
