During an illegal search, Commissioner Wally Wilson and Chief Inspector Robin De Rover seize a shipment of cocaine owned by Peno boss Patrick Paternoster. Wilson offers Paternoster a deal. While Wilson throws a wild party in the company of expensive call girls, Robin gets a tip about a major drug deal in the harbor.

Robin helps Nikki go into hiding. Then she gets bad news: Bob Martens, a violent drug dealer has turned up again. Martens still has a hefty bill to settle with both her and Nikki. Patrick Paternoster is eager to help Robin get Martens back to prison.

Patrick Paternoster wants to help a Russian gang take a large load of drugs. Then suddenly Bob Martens shows up. He suggests Paternoster to work together. Paternoster realizes he has no choice. Olga Martens is out for revenge. She wants to liquidate Robin and preferably as soon as possible.

Wally Wilson urgently needs money. He wants to mediate between the Russians and Paternoster in exchange for a hefty commission. Commissioner Frank Slaets sees through Wally's plans and sees his chance to catch him in corruption. Wally is suspended.

Wally Wilson remains suspended and has nowhere to go. Paternoster wants his four million back. Wally blackmails the Russians and sets up a trap. He begs Robin to help him make it, but then Nadia Camus must first ensure that he can return to work as a commissioner.
