One night in Manhattan, slick, up-and-coming press agent Sidney Falco scans the New York Globe for the column of the immensely popular journalist J.J. Hunsecker, an influential media kingpin whose journalistic contributions and associated radio show both dominate the entertainment world. For the fifth consecutive day, J.J. has neglected to publicize any of Sidney’s clients, as he is overly protective of his 19-year-old younger sister Susan and has asked Sidney to end her recent affair with Steve Dallas, a budding jazz guitarist.
Later, at the Elysian Room, where Steve performs with his group, the Chico Hamilton Quintet, Sidney argues with his uncle and Steve’s manager, Frank D’Angelo, who has promised him that Steve and Susan will part. Upon learning from his girlfriend Rita, a cigarette girl, that Susan is awaiting Steve behind the club, he interrupts the pair’s celebration. Steve, who mainly values integrity, angrily accuses him of “scratching for information like a dog.” Inside, Rita appeals to Sidney to help her retain her job, which is at risk because she refused to sleep with J. J.’s main competitor, the prominent columnist Leo Bartha, who then ordered her dismissal.
After Sidney secures a date with Rita, Susan questions his relationship with J.J. inside a cab, but he reassures her that J.J. is a close friend of his. Outside the 21 Club, J.J. greets his informer, Harry Kello, a corrupt police lieutenant, who is long indebted to J. J. for petitioning the mayor to save his job after Kello beat a suspect severely. When Sidney reveals Steve’s and Susan’s engagement, J.J. gives him an ultimatum to destroy their relationship. Desperate to salvage his career, he vows not to disappoint J.J.
Sidney attempts to blackmail Leo at Toots Shor’s Restaurant and Lounge by threatening to expose his marital infidelity with Rita unless Leo prints a defamatory gossip item stating that Steve is a Communist who smokes marijuana. Instead, Leo chooses exposure over compromising his journalistic integrity, which even his wife Loretta praises as his first decent act in years. Sidney then bribes another columnist, Otis Elwell, who agrees to print the item if Sidney will arrange for him to receive a sexual favor from an “available” woman.
At the Elysian Room, Sidney slips the cigarettes into the pocket of Steve’s coat. Once Steve finishes work that evening, Kello accosts him outside and so assaults him that he is hospitalized. At a bar, surrounded by his industry cohorts, Sidney celebrates his accomplishment but is then summoned to J.J.’s penthouse apartment.
As Susan packs her belongings, J.J. unsuccessfully begs her to stay; she coolly informs him that death is preferable to living with him. An overwrought J.J. watches from the balcony as she strides into the coming dawn to start life afresh with her lover.
