With Al Capone out of the way, the mob is looking to relocate its base of operations outside of Chicago in a nearby community. Their first step is to get rid of the incorruptible mayoral candidate, Judge Leon Zabo, who they run down in the street. The Coroner's inquest is a sham and it is obvious that the Chief of Police, who appoints the Coroner, is already in the syndicate's pocket. Ness and his men move into the town intent on shutting the mob down before they even get started but the Untouchables find that they also have to protect the dead Judge's daughter, Rosetta Zabo, who has taken up his anti-corruption campaign.
