Blackie (Chester Morris) is enlisted to help a friend whose nephew Jimmy (Steve Cochrane) has escaped from the asylum. Soon Blackie is face to face with Jimmy and discovers that Jimmy is obsessed with a young woman, and is also homicidally dangerous!
Jimmy kills a friend of the woman he is obsessed with, naturally Blackie's nemesis Farraday (Richard Lane) thinks Blackie has killed the woman. Blackie must try and save Sally (Nina Foch) who is now a prisoner of Jimmy and keep out of Farraday's clutches...
With two women killed and another in deadly peril, the usual Blackie and Runt (George E Stone) antics can sometimes jar a bit, especially when they go blackface! This is an enjoyable, if complicated, crime romp. The character of Jimmy brings plenty of menace.
