On Christmas Eve, a brother and sister are visited by the Fairy Berylune. The Fairy’s granddaughter is ill, and only the Blue Bird can save her. Berylune gives the children a wonderful gift that allows them to see the hidden essence of things. Inanimate objects — the Clock, Fire, Water, Bread — are transformed into living beings with their own personalities. Together with the children, they set off on a dangerous journey in search of the Blue Bird.
