Satirical gangster saga has criminologist Dr. Clitterhouse (Robinson) so fascinated by crime that he commits a few jewel robberies just to test out that bad guy rush. He contacts a fence, luscious Jo Keller (Trevor), who gets Clitterhouse an in with gangster Rocks Valentine (Bogart). Clitterhouse sucessfully masterminds some heists for Valentine--who becomes jealous of Clitterhouse's brain power and things just get more wacky from there (including a farcical trial). This is definitely Robinson's show.
