The feudal lord Kisaragi Yae no Kami (Minami Komyo) searches for a child he had with a low-borne woman, that was sent away from his home 16 years ago while carrying a special seal. At that time, Kanda's detective Zenshichi (Ichikawa Kodayu II) had three daughters, the third of whom, Omiyo (Misora Hibari), was a skilled singer and an expert with the lasso.
