Uncle Fyodor, a very independent urban boy, leaves the parental home with his new pet and friend, the economic cat Matroskin. Friends come to the village of Prostokvashino, where they get acquainted with the local dog Sharik, who points them to a free house. Parents of Uncle Fyodor give a note in the newspaper about the missing boy. This is learned by the rural postman Pechkin, who surrenders the boy to his parents in the hope of receiving a reward - a bicycle
Mom needs a vacation and a trip to the resort, because she is tired, and besides, she has nowhere to wear four evening dresses. Uncle Fyodor and Dad try to persuade her not to go to the resort, but to Prostokvashino, but Mom gets her way. Uncle Fedor decides to avoid a trip to the sea
Sharik and Matroskin quarreled and stopped talking to each other because Sharik, instead of felt boots, bought himself trendy sneakers. To carry the communication helps them the postman Pechkin, who transmits telegrams from one end of the hut to the other. Uncle Fyodor and Dad come to Prostokvashino on New Year's Eve (without mom, because mom should sing on the New Year's Blue Light).
