Don Camillo is outraged when his rival Peppone announces that their small Italian town of Breshello is to be twinned with a town in Communist Russia. When various attempts to overturn this decision fail, Don Camillo manages to persuade his superiors to allow him to accompany Peppone on his ceremonial visit to the Russian town. There, the Catholic priest is surprised that the country is not so religiously atheistic as he had imagined.
It was time for this saga to stop. Fernandel appears for the last time in this fifth episode in the long-running Don Camillo saga.
Ill-health prevented the actor from reprising the role for yet another film, which is probably just as well as the series had well and truly run out of steam by this time. Only the pleasing on-screen rapport between Fernandel and his co-star Gino Cervi prevents this entry in the series from being unbearably tiresome and stale.
