After Nitti shoots down Malone in his own home, Ness and Stone follow Malone's last words and pursue Capone's bookkeeper to Union Station. Following a bloody shootout, the bookkeeper surrenders to Ness, giving them enough information to put Capone on trial for income tax evasion. Ness confronts Nitti in the middle of the trial; after a rooftop chase, Nitti brashly admits that he killed Malone and Ness pushes Nitti off the roof to his death. A list in Nitti's possession reveals that Capone (Robert De Niro) had the jury bribed, so Ness intimidates the judge into switching juries. When Capone's lawyers realize that the new jury hasn't been bribed, they change Capone's plea to "guilty"; Capone goes to jail. Ness closes up his office and returns to his family.
