Kazokugari (2014)

Hizaki Yuko is a child psychologist working at the Childcare Center. At work, her heart goes out to the children at the center, especially so for the little girl Komada Reiko, who suffers abuse at the hands of her drunken father, Komada Koichi. At home, she has to endure the grumblings of her mother, Tamiko, who is the sole caregiver of Seitaro, Yuko's father suffering from Alzheimer's. With the suffering of the children at work and the complaints of her mother at home, Yuko can hardly get any rest and peace of mind. Sudo Shunsuke is a teaching art at a high school, but the days just flow by aimlessly for him. He dreams of creating a masterpiece and have his talent recognised by the world, and thus he spends all his free time creating his art. His girlfriend, Kiyooka Miho, is pressuring him to get married, but Shunsuke is reluctant to do so, as family and kids would just tie him down and stop him from realising his dream. One day, a crime takes place in Shunsuke's neighbor's apartment. The police had deemed it a murder-suicide, based on the suicide note left behind by the son, claiming that he had killed his grandfather and parents. Detective Mamihara Koki, based on his gut instinct, feels there is more to it, as the brutality of the parents' murder seems uncharacteristic of the child perpetrator. He decides to pursue the case further, and soon, Shunsuke and Yuko are unwittingly pulled into the investigations...
