On Christmas Eve, a little girl falls asleep after a party at her home and dreams herself (or does she?) into a fantastic world where toys become larger than life. Her beloved Nutcracker comes to life and defends her from the Mouse King, then is turned into a Prince after Marie saves his life.

Polish musical comedy. The film focuses on two friends who spend their vacation in the beautiful countryside of Mazury. They buy a very nice car (Syrenka), but in order to pay for it the men need to start working as solicitors for a notable art impresario named Koszajtis. Soon they get thrown right in the middle of a hilarious war between two rivaling music-and-dance groups.
