 In the thirties, during the Fascist Dictatorship, an insurance broker, Omero Battifiori (Nino Manfredi), reaches a small country town from Rome seeking for new customers. The main authorities, expecting an incognito inspection from the Fascist Party of the capital, suspect him to be the inspector and a very important member of the Party. The misunderstanding leads to a number of equivocals until Omero reveals his identity.
