On her tenth birthday Marianne runs a fever and to her horror she's soon confined to bed. She picks up a pencil and starts to draw to fill her time. That night Marianne Dreams. Transported into her own picture she discovers she has the power to change her dreams. As she draws by day and dreams by night, Marianne soon realises the consequences of her actions and finds that she's not alone - a sick boy called Mark exists not only in her dreams but also in her waking reality.
