The Untouchables

Robbins defies Ness's orders and investigates Capone's connection to a plan to take over Chicago's railroads. Pressured by Bureau of Investigation agent E.Q. Johnson, Robbins tries to convince Ness to look into the mysterious murder of two railroad police. Ness refuses, unwilling to get involved with the Bureau or to divert attention from Capone's expansion into Florida. Ironically, Nitti is also interested in the railroads, and has no more luck convincing Capone to listen. Convinced he is on to a sure-fire scheme, Nitti goes behind Capone's back and teams with a hood named Drenik to pay Lewis, a shady foreman, to run for head of the railroad workers' union.

Ness falls for a beautiful call girl while investigating a blackmail racket linking Capone to several noted court judges. The night before he is scheduled to appear before a judicial review board, Judge Ryan is found on the street below his luxury hotel room, the victim of an apparent suicide. Although a note is found in the judge's pocket, Ness and the Untouchables are suspicious. They learn that the judge spent his last night in the company of a young woman named Sybil, a model who works for CIeo Paine, whose agency is rumored to double as a high-class call-girl operation. Since every judge that is associated with a Capone case has been spotted with one of CIeo's models, Ness can't help but wonder if there is a connection and sets up a round-the-clock surveillance of CIeo's apartment. Watching Cleo from across the street, the just-divorced Ness can't help being struck by her beauty

The Capone ""family"" loyalty is tested when Frankie Rio's younger brother blows his cool and kills a member of a rival gang. Capone and his men are infuriated when police raid a party honoring Frankie Rio's mother's sixtieth birthday. The cops later apologize, explaining that they were given an anonymous tip that the party was actually the site of a secret arms deal. When the capos learn that rival gangster Aldo Genna provided that tip, Frankie's hot-headed younger brother, Johnnie, tracks Aldo to a restaurant and guns him down, killing an innocent waiter and wounding AIdo's brother, Mike Genna, in the process. The only person to see Johnnie's face is a restaurant patron, Professor Milton Revis, who rushes out in fear for his life.

Malone is targeted for murder by two gangland factions just as he reaches a decision to dramatically change his life. Disguised as priests, two gangsters burst in on an Irish communion breakfast to kill bootlegger Pauly Gaughan, slaying several children in the process. Sure that Capone is responsible, a rage-crazed Malone violently interrogates Vito Stellini, and is about to kill the gangster when Ness stops him. Stellini tells Capone what happened, and all agree that Malone is becoming a major problem. Later, Ness attends the wake for one of the slain children, where his father, Coffee Ryan, announces plans to kill the men who killed his son. Ness puts Ryan under surveillance, but realizes Malone poses a bigger threat. He finds his friend in a speakeasy, drunkenly threatening Capone and his cohorts. Later that night, Malone is assaulted and brutally beaten by four anonymous men, only to be saved from death by an Italian widow.
