A crime drama involving an attorney representing a 1920s crime boss and his henchmen when they run afoul of the law. The lawyer falls in love with a nightclub dancer who successfully encourages him to leave the mob, but not before he is wounded in a gang war attack, arrested, and forced to testify against the mob as a material witness. The mob then takes his girlfriend hostage to prevent his testifying, leading to an exciting climax. Must-see viewing for Charisse's steamy dance numbers.
