Maybe it is possible for a victim to forgive a perpetrator. But would it be possible for both of them to understand each other? Sato Yoshinori’s Her Mother tells the story of a mother who state of mind becomes increasingly complicated as she attempts to understand the son-in-law who killed her daughter. Harumi is a common housewife. One day she faces tragedy when her daughter Michiyo is killed by her husband Koji in their own home. Six years ahead of the court verdict, she starts to visit Koji in prison in order to see if her daughter, as she always wondered, did something wrong. She wants to know the truth. Talking to Koji, she begins to believe that Koji is the only one who understands her pain. But her husband and brother do not understand her at all, which stirs conflict among them. Sato portrays how a family changes after a daughter is killed and talks about family issues that have never been revealed before. In doing so, he shows that the line between the good and the bad is not clear but blurred.
