SHE DONE HIM WRONG

The story is set in New York City in the 1890s. A bawdy singer, Lady Lou, works in the Bowery barroom saloon of her boss and benefactor, Gus Jordan, who has given her many diamonds. But Lou is a lady with more men friends than anyone might imagine.

What she does not know is that Gus traffics in prostitution and runs a counterfeiting ring to help finance her expensive diamonds. He also sends young women to San Francisco to be pickpockets. Gus works with two other crooked entertainer-assistants, Russian Rita and Rita's lover, the suave Sergei Stanieff. One of Gus's rivals and former "friend" of Lou's, named Dan Flynn, spends most of the movie dropping hints to Lou that Gus is up to no good, promising to look after her once Gus is in jail. Lou leads him on, hinting at times that she will return to him, but eventually he loses patience and implies he'll see her jailed if she doesn't submit to him.

A city mission is located next door to the bar. Its young director, Captain Cummings, is in reality an undercover federal agent working to infiltrate and expose the illegal activities in the bar. Gus suspects nothing; he worries only that Cummings will reform his bar and scare away his customers.

Lou's former boyfriend, Chick Clark, is a vicious criminal who was convicted of robbery and sent to prison for trying to steal diamonds for her. In his absence, she becomes attracted to the handsome young psalm-singing reformer.

Warned that Chick thinks she's betrayed him, she goes to the prison to try to reassure him. All the inmates greet her warmly and familiarly as she walks down the cellblock. Chick becomes angry and threatens to kill her if she double-crosses or two-times him before he gets out. She lies and claims she has been true to him. Gus gives counterfeit money to Rita and Sergei to spend. Chick escapes from jail, and police search for him in the bar. He comes into Lou's room and starts to strangle her, breaking off only because he still loves her and cannot harm her. Lou calms him down by promising that she will go with him when she finishes her next number.

After Sergei gives Lou a diamond pin belonging to Rita, Rita starts a fight with Lou, who accidentally stabs her to death. Lou calmly combs the dead woman's long hair to hide the fact Rita is dead while the police search the room for Chick Clark. She has her bodyguard Spider, who "would do anything for you, Lou" dispose of Rita's body. She then tells Spider to bring Chick, who's hiding in an alley, back to her room upstairs. Then, while she sings "Frankie and Johnny", she silently signals to Dan Flynn that he should go to her room to wait for her, even though she knows Chick is in there with a gun. Chick shoots Dan dead and the gunfire draws a police raid. Cummings shows his badge and reveals himself as "The Hawk", a well-known Federal agent, as he arrests Gus and Sergei. Chick, still lurking in Lou's room, is about to kill Lou for double-crossing him, when Cummings also apprehends him.

Cummings then takes Lou away in an open horse-drawn carriage instead of the paddywagon into which all the other criminals have been loaded. He tells her she doesn't belong in jail and removes all her other rings and slips a diamond engagement ring onto her left ring finger.

Captain Cummings reveals himself as a federal agent, arrests the criminals in Lou's orbit, and prevents Chick from harming her, ending the web of crime surrounding the saloon.

The film concludes with the exposure and arrest of the criminal elements that fueled Lady Lou’s glittering lifestyle. Cummings’s undercover work brings justice to the Bowery, and Lou’s navigation through a minefield of dangerous men finally pays off. The ending ties up the central conflicts—Lou survives the threats of jealous lovers and criminal partners, and the authorities sweep away the corruption, leaving her fate intertwined with the enigmatic Captain. It’s a wrap on vice and a wink to redemption, 1930s-style.
