The Runt is getting married—that is, if his and Blackie's wealthy friend Arthur can manage to keep the few principals involved in the wedding assembled in his house for more than thirty seconds. Blackie, however, is occupied helping an old friend's daughter sort out a mystery involving the missing father, some diamonds he had hidden and a gang of crooks who will stop at nothing to seize those diamonds. Of course, Inspector Farraday and his dumb assistant Matthews are on hand, slapping Blackie with any charge handy and letting Blackie slip away as needed to work on the actual solving of the case.

Cy Kendall is particularly oily as the head villain here, even though he had appeared in at least two previous series outings as an old underworld pal of Blackie's. Walter Sande as Detective Matthews is wonderfully hapless as comic foil and brunt of insults for both Farraday and Blackie. (Farraday making a point: "I have Matthews as a witness!" Blackie: "Well, I wouldn't brag about that.")

A handful of comments and events in the film allude to the war—particularly a scene set during a blackout when cops, bad guys and Blackie and friends are all chasing each other around in the dark. But for the most part, this is your standard escapist B mystery featuring familiar characters, plentiful comic relief and an easy-to-follow plot about diamonds and murder.

We never do find out if Blackie's "ulcer remedy" that he shares with Farraday is the real stuff, or just a trick. I suspect a trick, since one of the ingredients is ketchup.
