Blue is the dominant color in the cold, sterile world of adults. 12-year-old Maria dreams of other colors beyond blue. In her dreams, she repeatedly sees a boy in a castle who asks her to play a piece on the piano for him. When she fails, the castle goes up in flames. On her explorations in the real world, Maria finds the castle and the boy from her dreams again. He is lying in a coma in the intensive care unit of a clinic. Maria tries to bring him back to life through her music.
