Minna is a young girl who lives out in the rural country with her father, John, her mother Karen having left them to pursue her career as a singer. Minna struggles to adjust to the arrival of John's new wife, Helene, and her daughter Jenny, who regularly quarrels with Minna. While dreaming one night, Minna discovers a hole in the sky and notices blue creatures controlling her dream, who abruptly wake her up. Minna investigates the following night, discovering the blue creatures are Dreambuilders, responsible for designing peoples' dreams, and meets Gaff, her Dreambuilder. While hiding from the Inspector, Minna is knocked off her dream stage and into her father's, inadvertently altering his dream when she hands him a can of anchovies instead of the cake as was scripted.
