A lady who had a secret affair lives in fear.

19th Century Russia. State prosecutor Fedor Andreiev is presiding over the trial of a man who murdered his wife's lover. Despite a robust defence from the brilliant young lawyer Serge Rostoff, the accused man is found guilty and will be deported to Siberia. Having spoken to the condemned man, Fedor Andreiev sees a disturbing parallel with his own life...

Marie Leroux, who is married to Charles, an honest, understanding country doctor, lives an uneventful, rather monotonous life.Her husband is a kind man but he does not give her any thrill or excitement. One day, Marie meets Olivier Dumas-Beaulieu, a handsome industrialist, who is in the process of leaving his fiancée Corinne, despite her being pregnant by him. It is easy for the confirmed womanizer he is, to seduce Marie, who very foolishly thinks she has found true love. Shortly afterward Charles is shot dead by Olivier while the two men were having a quarrel about Marie. The latter, who finds the corpse, believes her husband has committed suicide. Which is not the police's opinion and Marie is arrested and condemned to ten years in prison. Annihilated by such unfair treatment and, worse, by the separation from her beloved eight-year-old daughter, she still manages to survive and to serve her sentence.
