By the Summer of 1933, a new wave of crime has engulfed Chicago. Due to a public outcry for action, Willard Thornton is appointed as a new commissioner to clean up the town. At a press conference, Thornton arrogantly says his office does not publicly constitute criticism of any law enforcement agency-- while his tone of voice implies he privately does criticize them. Eliot Ness is standing right next to him, looking more dour than usual.
Ness and his men go on a raid, they find a shipment of heroin in a hideout.
