The 13th in a series put out by Columbia in the "Boston Blackie" cycle. Morris and his amiable runt buddy, Stone, are in charge of guarding some priceless jewelry that is then stolen, with all the evidence pointing to them as the culprits. The film follows formula as they hunt the real
thieves. Morris and Stone put on disguises, once as an older couple, and that is so old hat in the series that the story sags a bit.
