Plot Summary

In 1961, in the quiet village of Kuzuo, five women died after drinking wine at a community gathering. Masaru Okunishi, then 35, was arrested. He was first found not guilty, but later sentenced to death based only on a written confession taken under suspicious circumstances—despite no physical evidence. Okunishi insisted on his innocence until his death in prison at 89. His sister, Miyoko Oka, now 94, has spent her life trying to prove it, submitting ten appeals with new evidence—all denied. Under Japanese law, only close family can request a retrial. With limited time left, she continues to fight for the truth.
