After receiving a tractor as a gift from the kolkhoz of an unnamed Soviet village, communist mayor Peppone plans to twin Brescello with the unnamed town. After some failed attempts to block the major's plan, Don Camillo ultimately tricks Peppone into including him (under a false name and with forged papers) among the Italian communist representatives going on the other side of the iron curtain to attend the twinning ceremonies. Only Peppone and the other comrades from Brescello will know the priest's real identity. During the Russian stay they will face a series of situations that will show them both the political contradictions of Soviet Russia and the normal life of its common people.
