Leuven university student Tessa Vermeersch, a test person in a diabetes drug trial, goes missing. her father, procureur (D.A.) Anton ignores here whereabouts. The day before, as sadistic pledge-master with lover De Ridder, she ordered freshman Koen 'Ketchup' Cuyaerts' genitals exposed and smeared during a public hazing orgy. Since the Weemaes case, Steve and Nick's rapport is affected, but they make up. Koen saw Tessa being visited by the Moroccan father of her friend Dashia Boussedra, about keeping her rape secret, it's not the only one, and Tessa's abuse is hard to tackle. Especially given Tine's procedural clumsiness. But Steve cunningly finds an 'unofficial' angle to a family complication.
