An accident leaves Sue with no memory of her past, and Torao's family takes her in. She has always felt driven to become a singer without knowing where that urge comes from. The answer lies in her history: Sue is a member of a band she formed with her two twin sisters. Reaching the top of the charts proves to be a long, difficult climb. This short-format musical adventure from 1980 is an early example of idol anime, and it drew its inspiration from a popular 1979 novelty disco song that also serves as its ending theme.
