Although Mary (Isabel Huppert Isabelle Huppert) is now a mother of two, she is still mentally like an ignorant child who has not received any formal education since childhood. Mary's husband Paul (Francois Cruise Fran ç ois Cluzet) is a soldier. In a turbulent situation, he is sent to the front to take part in the war. He has not returned, leaving his wife and children to live in poverty and hardship. Mary helped a woman to have an abortion and found a business opportunity. In those days, abortion was illegal and assisted abortion was a capital crime. But under the pressure of life and the temptation of money, Mary still took up this illegal and dangerous job. By chance, Mary met a man named Lucian (Nils Tavernier), and the two fell in love at first sight, so they began an immoral love. Unexpectedly, Paul saw through the adultery between the two after his return. Angrily, he reported all of Mary's actions to the police. What Mary will face is the death sentence.
