Three vixens have meditated for 1,000 years to able to shed their animal
natures and become human. For the final month of their rigors, they have moved
near a village where women pray to a god of fertility. One sister visits the
god's temple and thinks lustful thoughts. As she leaves, a priest confronts
her, warning of dire consequences and of demons that will try to stop the
vixens' transformation.
Soon, the youngest sister saves a poor scholar from bandits and becomes
enamored of him. Each sister visits him, and before long, the youth has made
love to all three. After they invite him to stay with them, the playfulness
takes a scary turn. Where can they turn for help?
