A professor of psychology maintains a soup kitchen in the Bowery. Secretly, however, he’s also a gang boss who uses the soup kitchen to recruit members for his organization. One such recruit is a doctor who has become addled and addicted to drugs and alcohol. The doctor, however, happens to be quite adept at corpse reanimation!
There is a scene in the movie where a couple of policemen are standing outside a cinema. If you pay attention you can see a movie poster for the movie The Corpse Vanishes. A horror movie that Bela Lugosi also stared in prior to Bowery at Midnight.
