In the Siberian village of Yartsevo, there's a boarding school. Every autumn, about thirty children of Old Believers from various villages come here to study. From a familiar world with a set of strict rules, the teenagers find themselves in an environment full of temptations. Studying away from home often becomes a challenge for them. Helping them cope is provided by the nannies who work at the Yartsevo boarding school. They temporarily act as the children's parents.
