The film tells about a simple, gullible, not very successful rural inventor from the village of Dubrovka - Dmitriy Pryazhkin. The main character is always making something and fixing everything that comes to hand. But not all the inhabitants of the village share his hobbies. Unable to withstand his constant "inventions" (which have already become nocturnal), his own legitimate young beautiful wife Ulyana left him.
