Reputable lawyer Piron and his junior apprentice Struye competently win a case by exposing arrogant detective John's procedural errors. The next night, Struye is murdered at a crime scene. The prosecutor wisely guards the delicate case's ethics and invites the bar association's chief to supervise the confidentiality aspects. The team discovers various tensions within the law firm, such as the secretary having switched lovers to Strye from the junior partner Claes, and Piron's own possibly dodgy past.
