October 11, 1932.  Chicago.  Less than one month before the elections, David Mantley, running for State's Attorney on the Reform ticket, is making speeches: he says the power behind his opponent, Jeremiah Down, is mobster Bryan O'Malley.  At the same time, across town, O'Malley is being feted at a testimonial dinner-- even though a week from now he'll have to stand trial for murder and income tax evasion. After Mantley's speech, and the small crowd has left, a speeding car goes by, and a chopper riddles Mantley full of bullets. Ness and his men are on the case. Henry Weiser is meeting with his boss Bryan O'Malley; it was Weiser who had Mantley rubbed out.  O'Malley's murder trial (for the contract killing of Rocky Marlos) is in 4 days, and Ness will help the prosecutors; there are 2 witnesses who could get him convicted: George Davas and Stan Willinski, former associates of Weiser.  O'Malley thinks they can scare Davas into not testifying, by getting to his girlfriend Julie Duvall.
