Rosie wakes up in a monochrome world, with a dark cloud over her head. As she plods through her miserable, gray day, the cloud follows. Mishaps and mayhem thwart her every move, irritating noises assault her - and the pouring rain makes everything worse. But then, on her way home from school, Rosie finds a pair of strange glasses. When she puts them on, her world transforms into vivid, joyful colour. All of a sudden, she can see the beauty and fun in everything around her - and her dark cloud has disappeared. Are the glasses magic?
