In 1961, a spectacular criminal case shocks Japan: at what became known as the “Nabari Poison Wine” incident, five people lose their lives at a village social gathering. One of the attendants, Masaru OKUNISHI, is made out as the main suspect. Rumor has it that he wanted to kill his wife and his lover in order to end his extra-marital affair. After being questioned by the police for days, he signs a confession, only to withdraw it soon afterwards. Nonetheless, he is sentenced to death and all pleas for a retrial are denied.
