As St. Nicholas Day approaches, St. Nicholas and his helpers are busy preparing to grant children's wishes at a cozy hotel nestled in the Carpathian Mountains. But their preparations take an unexpected turn when they discover a letter that has been lost and left unread for more than 30 years.

The letter was written by Borya, a young boy living in an orphanage, whose wish was never granted. Over the years, Borya grew up and stopped believing in miracles. And as his faith faded, so did the magical powers of St. Nicholas. Now, the mistake must be corrected before the holiday arrives.

St. Nicholas's helpers set out to find Boris, the grown-up boy who wrote the forgotten letter. But he is no longer the hopeful child he once was. Now a wealthy, cynical investor, Boris believes neither in love nor in family.

After an unexpected accident, Boris begins seeing a nine-year-old boy by his side — his own childhood self. With St. Nicholas Day fast approaching, Boris must finally fulfill his childhood dream. If he fails, he will lose his ability to experience joy forever, and St. Nicholas will lose his magical powers.
