We're a family.

After the sudden death of her mother and stepfather, student Lilya remains the only close person for her younger brother and sister, the clever Sema and the bully Masha. Lilya herself cannot take custody of the children: she has neither housing nor a stable income. To prevent them from ending up in an orphanage, Lilya turns for help to Andrey, the eldest son of her stepfather, with whom she has a long-standing conflict. Andrey blames Lily's mother for destroying his family.
