A science-fiction fantasy based loosely on the classical Japanese Noh theatre drama Adachi-ga Hara about the demon Onibaba, of which lyrical extracts are quoted at intermission-like intervals throughout the film. The plot centres on a journey made by a space pilot named Yūkei who arrives at a planet upon which a murderous "witch" is said to reside.
