Une page d'amour

François (Sami Frey), a Jewish lad, works for an insurance company and is engaged to a Jewish girl. His world is very ordered and secure and perhaps feels a bit claustrophobic. When he observes that a murderer has been declared psychologically incompetent and is to be placed in a mental institution, probably for the rest of his life, François feels the murder's plight very keenly. As time goes by, the murderer's situation is more and more unbearable to him, and he breaks off his engagement. Afterward, he has a liaison with a girl he has not known before, an act that somehow frees him. Now he wants to free the murderer somehow.
