In the first episode of a two-part story, Capone lieutenant Frank Nitti (Bruce Gordon) attempts to bribe Chicago mayor Anton Cermak (Robert Middleton) for a piece of the 1933 World's Fair. When Cermak tells him to get lost, Nitti growls "You're dead"--and he means it. As Federal agent Elliot Ness and his Untouchables provide Cermak with round-the-clock protection, Nitti brings in a couple of out-of-town boys to assassinate the Mayor...while a deranged lone gunman named Giuesppe Zangara (Joe Mantell) plans a killing of his own. Parts One and Two of "The Unhired Assassin" were later combined and released theatrically as the feature film Guns of Zangara.
