Chimaki is a cheerful little girl who lives in Japan. One afternoon, she studies so hard that she works up a big appetite. She rushes home for an after school snack and when she arrives, smells her mother's freshly baked chocolate chip cookies, Chiamki's favorite! She runs into the dining room and grabs the cookies without even washing her hands! What happens next she could not have imagined. Her cookies disappear!! Where did they go? She must find out who took them and why anyone would ever do such a thing.
