Boston Blackie indulges in some wit-trading with a squirmy spiritualist who deals in blackmail, murder and the occult. "Blackie" out to help his pal, "Runt," recover some jewels, finds himself involved in the homicides, and also finds himself as the prime suspect, and now has to find the real culprit in order to clear himself. So "Blackie,", a man of many talents, shows he knows a little bit about dancing skeletons, walking phantoms and spiritualism himself, and holds a séance to unmask the murderer.
Jewel theft, seances, murder, trapdoors, spooks, blackmail and murder - it's all here in this light crime quickie. It's a fun film with Boston Blackie and the runt getting into trouble and murder. Love the snappy dialogue and the busy plot.
