Lucy is a six-year-old girl who hates mathematics and, not surprisingly, she does not understand the point of doing homework. One night she hears someone sobbing in her room, and, curiosity exceeding her fear, she looks in the wardrobe. There, she discovers Bruno, the child ghost. They become friends and together solve the maths problems set for them by their teachers, share reading material and, in short, overcome life?s little teething problems.
