Pasha and Liza have been married for 20 years. In their youth, they made a contract with the Wizard. He granted them magical powers in exchange for one condition: Pasha and Liza would spend exactly 20 years together, not a day more, not a day less. After that, they would either separate voluntarily—forever—or be separated by death. But the time has come to fulfill the contract, and Liza and Pasha still love each other and don't want to part. They have two beautiful children, Masha and Petya. Pasha and Liza are looking for a way to break the contract, and their children, upon learning of the divorce, try to "save their parents' marriage" by interfering with them at the most inopportune moments.
