Boston Blackie gets involved with the hunt for missing diamonds.
Ed Barnaby (Walter Baldwin) leaves prison after the theft of diamonds which were never recovered. He knows the mob will be after him and the loot so sends his daughter Betty (Ann Savage) to enlist the help of his old pal Boston Blackie (Chester Morris). Herschel (Cy Kendall) and his thugs end up killing Ed and then kidnapping Betty in order to force Blackie to give them the diamonds. Hapless Police Inspector Farraday (Richard Lane) as, as always, a few steps behind.
This is another fast moving, rich yet straight forwardly plotted, crime romp with plenty of good humour including a side-plot of The Runt (George E Stone) trying to get married. A highly enjoyable film.
