A psychedelic Soviet/Estonian animation short. A hare boy doesn't want to go to sleep in the evening. His mother tries to scare him with a fox, a wolf and a bear, but he is not afraid of any of them. Suddenly, a small mouse appears on the floor - and the hare boy goes quickly under the blanket.

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.
