In the heart of the justice system, respected magistrate Simon Cordier has a haunting encounter with Louis Girot, a condemned prisoner on the brink of execution.

Meanwhile, he is drawn into a complex relationship with Odette, a calculating woman married to a floundering artist, whose allure is as golden as her ambitions.
