Synopsis

Iori, a 16-year-old boy, is forced to commit "seppuku" (ritual suicide) to follow his late sovereign in death and thus preserve the honor of his samurai clan. His older brother's wife, Oko, who raised Iori as if he were her own son, asks her husband's permission to spend a night with the young man and teach him, out of maternal mercy, the art of pleasures of the flesh. However, the next day, an official decree is issued, surprising everyone involved.
