One day, lawyer Takamori Takiko gets a request from a women’s organisation to take a case. Insurance saleswoman Sumura Satoko has been arrested on suspicion of murdering her husband Yokichi, who is out of work and a bad drunk. Yokichi got drunk on the night he died. He hit and kick her and would not stop. Satoko says she killed him in order to protect their son Takashi from domestic violence. Since the perpetrator was a victim of domestic violence and the unemployed husband was financially dependent, the rights of women become the focus of this case.
