Molly Louvain is a young woman who has a baby out of wedlock. She falls in with a career criminal and, after he is shot by police, she hides out with a former bellhop who wants to marry her and make her "respectable." But, instead, she falls in love with Scotty Cornell, a fast-talking cynical newspaper reporter, who does not realize that she is, in fact, the very gun moll that he has been writing about in his columns. As she is about to go to prison, he discovers her identity, but pledges to stick by her nevertheless.
