Gangs of Chicago is a 1940 crime film, starring Lloyd Nolan, Barton MacLane, Lola Lane, Ray Middleton, Astrid Allwyn, and Horace McMahon.

With a federal agent named Evans keeping a close eye on his activities, Matty becomes the legal mouthpiece of Jim Ramsey, a racketeer.

Ramsey and his moll, Virginia Brandt, don't trust Bill and spring a trap, catching him red-handed seeking evidence.

[6] The Los Angeles Times said Nolan and Middleton are "very good, but it is really Lola Lane... who rings bells.

"[7] The New York Times called it "a stock cops and robbers melodrama... the only surprise in the picture is the sincere performance turned in by Ray Middleton.
