Acting Saint Nicholas: One week before St. Nicholas Day, St. Nicholas writes an application for sick leave. All gifts for polite children are ready, except for one: a 9-year-old girl Yustia did not write him a letter with her wishes. The same is due to his hospitalization and the fact that no child can be left without a gift, St. Nicholas assigns his responsibilities to the girl's father. The girl's father is a musician and composer who, after the death of his wife (the girl's mother), no longer plays music, but tries to make a career as a presenter, forgetting about his child's dreams.
