A film by Nelvana with a little girl who sees a little polar bear at the zoo and has a dream about the polar bear. The bear shows up at her window one night and invites her to ride his back while he flies through town. She takes the polar bear in her home and tries to hide him from her parents.
The music sounds like classical orchestra music. The whole film is silent except for music.
