A lawyer called Yamauchi is arrested and charged for his wife murder. During the trial, he will be represented by another attorney called Kuramoto. Among Kuramoto's acquaintances, voices rise up saying the Yamauchi were really cheerful towards each other, so the probability of the husband killing the wife is really low. In order to investigate the case, Kuramoto will travel to Aso (where the murder took place) and meet the couple's daughter and visit temples.
