The title should be understood, according the director Sergio Corbucci, as "What Am I Doing in the Middle of the Western Cinema?". It is the final chapter of the Corbucci's trilogy about the Mexican revolution, after The Mercenary and Compañeros. The film mixes comedy and political apologue.
Theatre director Don Albino Moncalieri and his only employee Guido Guidi are in desperate need of money. They comply immediately when they are hired by a certain Peppino Garibaldi, who seems to be a relative of famous Giuseppe Garibaldi. On tour throughout Mexiko they get by accident entangled in revolutionary activities and experience the fog of war.
