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.

The frustration at the Drugs Cell is great now that Bob Martens is walking around freely again after a series of procedural blunders. Wally Wilson is no longer under control of his drug and sex addiction. Commissioner Frank Slaets interrogates Martens, but soon lets him leave on the order of the investigating judge. That same evening, an intervention led by Slaets gets completely out of hand.

Robin is convinced that Bob Martens is behind the kidnapping of Lissa. She asks Paternoster for help, but he wants something in return. Then she unexpectedly receives a tip from Frank Slaets. Nadia Camus informs Bob Martens that she no longer wants to be his lawyer. She should not have done that.

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 is out of control of his addictions. Robin has less and less control over him. Paternoster is 4 million poorer because of Wally? S debt. He plans revenge, but will have to hurry because the Russians also want to deal with Wally. They're sending an assassin on him.

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.
