Однажды летом

Ilf and Petrov's only work in cinema is a comedy about the adventures of two passionate car enthusiasts during a road trip. On their way to Moscow in a car assembled from scrap materials, they meet a charlatan—a "professor" with a pretty niece. Convinced that the "professor" is a common swindler, the friends turn him in to the police, while they themselves continue on their way with the girl and are the first to reach one of Moscow's squares—the finish line of the road trip.
