The Girl From Chicago on AllMovie

The plot to this underworld drama, based on a story by Arthur Somers Roche, sounds more like something from the 1930s than from the silent era. It's an early starring vehicle for Myrna Loy. Southern girl Mary Carlton (Loy) finds out that her brother, Bob (Carroll Nye), is going to the electric chair for a crime he says he didn't commit. In order to get her brother exonerated, Mary travels to New York and pretends to be a Chicago gun moll. She wins the love of two gangsters, Handsome Joe (Conrad Nagel) and Big Steve Drummond (William Russell). Joe, it turns out, isn't a gangster at all, but an undercover detective. He attempts to help Mary prove her brother's innocence, and the two of them are caught in a fierce gun battle between the crooks and the cops. They make it through alive (although Drummond gets his due), and Bob is released at the last minute.
