The Blue Room (15)

Julien Gahyde is trapped in an unedifying marriage with his wife Delphine, which inflames his self-loathing. He seeks solace in the arms of a mistress, Esther Despierre, who is also married, knowing deep down that they can never be together. When Esther’s husband meets a grisly fate and the finger of suspicion points squarely at Julien, the adulterous husband faces a barrage of questions from a police officer, a psychologist and a judge in an effort to expose the shocking truth.
