In Québec City, Québec, the exiled German Otto Keller confesses to the Catholic priest Michael Logan late night in the church that he has just killed the lawyer Villette that employed him as gardener to steal two thousand dollars dressed like a priest. Meanwhile, the arrogant Inspector Larrue, who is in charge of the investigation, discovers two teenagers that have witnessed the killer dressed like a priest sneaking out Villette's house and walking to the church. When Larrue sees Father Logan talking to Ruth Grandfort near the crime scene, he summons them to a hearing at the precinct. Ruth provides an alibi to Father Logan telling that they met each other during the night. Further, she also tells that they had a past together before the war, and also that Villette was blackmailing her due to a secret meeting she had with Father Logan, when they spent the night together. Father Logan keeps the secret of the confession, but Ruth unintentionally provides the motive for the murder, and the prosecutor Willy Robertson uses it in court.—Claudio Carvalho, Rio de Janeiro, Brazil
