Testimony of Evil

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.

Un malfrat notoire et influent parvient à faire assassiner un de ses deux témoins à charge par un policier corrompu. Ness et ses Incorruptibles doivent retrouver la petite amie de la victime avant les gangsters pour qu'elle serve de second témoignage.

Ness trata de localizar a un testigo -que se oculta de la ley y de la mafia- cuyo testimonio puede condenar a un gánster e influir en una elección.
