The Lonely Gun tells of Johnny Vickers, an Arizona newspaperman who is now a fugitive accused of murdering a rival newspaperman. Judge Kern, who has been aggressively pursuing Vickers, has arranged a clandestine meeting with Vickers. The judge s daughter has been kidnapped by a party of Apaches and the judge is offering amnesty to Vickers if he can rescue the girl. Vickers is uniquely capable of doing this because of his friendly relations with the Mokis, but there are those out there who plan to make sure he fails."
