Возвращение Мухтара S11E20 - Хранители

Ekaterina's brother, Igor, a geologist, invites his sister to spend the weekend in the Moscow region. She takes Maxim and Mukhtar with her, and for good reason! Igor's friend, the director of the local museum of Local lore, informs them that a 12th-century silver scabbard has disappeared from the museum, and one of Repin's sketches has been replaced with a copy. Katya and Max take on the investigation of this theft, and they are helped by a funny mongrel, Asya, the dog of an employee of the Ignatiev Museum.
