Wastrel Larry Grayson constantly drains his wealthy father Henry Grayson's fortune to spend the money in a speakeasy where singer Sally Curtis entertains. Gangster Joe Hardy tells Sally to befriend Larry so that he can pin a murder rap on the young man. Larry winds up getting framed for the shooting murder of nightclub owner Felix Brown (Lugosi), and his wealthy father turns him over to the police. A criminal trial results in the young man receiving a suspended sentence and a lengthy lecture about how "partying and jazz music" can lead to the downfall of youths.
