A corpse found floating in the river Maas is identified as city official Harold Decleir. Wolf works out how to link his murder with building serious, lucrative offenses involving major contractor Herman Kuyper. Romeo is furious, feeling passed over by outsider Daan de Vos as new detective, but has to work him in. Their s-approaches conflict from the first case, a gang of troublesome seniors bothering a shopkeeper.

Realtor Julian Donkers is found hanged by a colleague who showed round the Canadian Matthews couple, which he was supposed to receive in that house. Wolfs works out the firm or its regular contractor Paul van Rossem are making impossibly hight renovation profits and finds out those homes were sold by people in Flemish sub-standard retirement home De Engel. Novice inspector Daan de Vos's zeal in a theft prevention campaign backfires most embarrassingly, but he resolves to set it right.

After four rape cases in sheltered areas around the city, Wolfs convinces the commissioner to set a trap with Eva as voluntary bait. While the team is distracted by habitually bothersome citizen Pieter Hofman and Wolfs by the discovery of his daughter Fleur with a heroin OD, the real rapist seizes Eva to his underground den. The desperate search focus on known sex offenders, but alas not only the team's.

Dodgy beat cop Arnold Wijffels, moonlighting as security for the Maastricht golf club, is shot there. Shortly after, two corpses, also shot, are dragged from the river. Although Wolfs has to deal with his daughter's relapse in rehab, he soon works out it's all about Turkish drug-trading street gangs, one of which operates from over the Belgian border. The part of wayward dropout youngster Ab de Groot, whom evidence situates on the cop murder spot, his roughing-up and his genealogy prove the key.

Improbably successful local investment consultant Guillaume 'Will' Degryse's daughter Julia's fiancé is reported missing during a visit to the Maastricht 'kazematten', in historical fortification tunnels. 'Uncle Wil' says he spared the man prosecution for malversation for Julia's sake, but Wolfs works out both his investment strategy and linked art businesses are dodgy. Later the victim is identified as another man and Will's wife disappears, allegedly with a lover and a fortune. Meanwhile Daan gets some basic training in a handbag and cellphone theft case, which turns out to be something else.

The police arrests adolescents Loretta Verstegen and her best girl friend for a public knife fight. Leisures suggesting abuse are found on her, but only after much pressure she makes a declaration that her slick boyfriend Robbie Aerts occasionally hit her, quickly followed by a claim instead hat Wolfs sexually abused her. Daan and Romeo check on fake alarm calls from a journalist's private cellphone for which he blames his three children. Eva's disloyalty now extends to initiating a formal investigation whether Wolfs stole a fortune in cash.

Wolfs is suspended and jailed pending an examination how the stolen cash came into his home. A computer expert's findings and Romeo's own observations bring the precinct to question supposedly software-ignorant Daan. Wolfs is cleared and liberated, but runs straight into a murderous trap. Then only Daan explains why he hates Wolf on account of a case from years before he entered the police academy.
