Un Honnête commerçant

The police are questioning Hubert Verkamen, suspected of murdering an entire family. Although he presents himself as an honest businessman, the cops know full well that he's nothing more than a dangerous drug trafficker. Having never succeeded in catching him, they are delighted to finally have the opportunity to arrest him, and use every means at their disposal to make him talk, to wear him down. But the manipulation is not where they expected.
