After receiving a tractor as a gift from the collective farm (kolkhoz) of a Soviet village on the Don River, Communist mayor Peppone plans to twin Brescello with the unnamed village.

After some failed attempts to block the mayor's plan, the anti-Communist Don Camillo ultimately tricks Peppone into including him (under a false name and with forged papers) among the Italian Communist representatives passing through the Iron Curtain to attend the twinning ceremonies.

Only Peppone and the other comrades from Brescello know the priest's real identity.

During the Russian stay, they face a series of situations that will show them both the political contradictions of Soviet Russia and the normal life of its common people.
