Undercover - Season 1

The police knows Dutch synthetic drugs king Ferry Bouman ruthlessly heads his syndicate from Belgian Limburg. After leg-chained drug lab Anh Dung and Chan have a fatal fight, the survivor makes a run for it after butchering the other. Henchman Remco Engels, who poorly supervised them, is ordered to find and catch him, but is too lazy and stages the fake killing of another Chinaman, so Feryy and his deputy John Zwart decide to execute Remco. Meanwhile Belgian justice decided to attempt approaching slippery Ferry, whose villa is a fortress, by undercover on his favorite camping site. Belgian by-the-book detective Bob Lemmens accepts the job, soon regretting to be paired with Dutch maverick daredevil Kim De Rooij, who does however know how to bond with ferry's sissy wife Danielle, who invites them to a barbecue.

After a month, the brass worries the undercover produces only expense accounts. Cocky henchman Jurgen Van Kamp keeps provoking Bob, who can't resist putting the macho in his place, which causes public, strife. Drug baron Ferre scolds 'vague' police mole Walter Devos and Jurgen, who misses out on promotion to drug lab supervisor, but also tells Bob 'too much like I was' to stay out of the way. Handler Nick decides the better option now is Ferre's superstitious, gullible wife Danielle Bouman, whom Kim is to save from a fake mugger, but she makes a bad fall and panics over her runaway pooch, so Bob has to help find and return it.

The mission looking like a complete failure as Ferry told them to leave the camping, Bob now refuses to team up with unruly Kim, who still agrees to help out keeping contact with Ferry's wife Dani. Bob now helps out cleaning up after Jurgen's nightly accident under influence and poses as an intercontinental import-export businessman, whose 'empty cargo space' should prove handy for contraband drugs. Alasn all he's actually offered are the Italian designer suits Ferry's deputy John and henchman Jurgen stole 'as down-payment' from fancy fashion dealer Gino Maldini, who posed a big client but is found out being a front for a German mega-dealer.

Just when Bob and the brass are ready to pull the plug on the undercover job, Kim's lesbian rapport with Danielle makes her work on Ferry to invite them to move into a cabin on the camping ground. Bob even neglects his wife mourning her father as he also gets to offer over a Chinese dinner with the drug baron and the girls his 'shipping firm' services to a major transport, at last. It's for the new German bulk client Bastian Gerlach, who agrees to deal with them after having cutting out the Italian middleman, although that burnt sucker is his in-law. However Bob can't wriggle out of working blind, as the terms are changed last-minute due to Ferry's mole duly reigniting suspicion. Justice refuses to wait and uses Bob's first tip for a raid to major supplier Frank Goossens. Klutz Jurgen is assumed the only plausible rat and dealt with by his won father in law, John.

Bob has to travel to Poland to fetch a shipment of PMK for Ferry, but John gets him into trouble. Kim is feeling guilty when she learns that Jurgen has been murdered. Bob single-handedly has to try and save the operation, but nothing is what it seems.

Bob and Kim feel guilty at Jurgen's funeral. John reverts to old habits after seeing his daughter's grief. Ferry asks Bob to accompany him to a deal with an important German drug dealer.

John wants revenge for the assassination attack on Ferry. Bob accompanies John in an attempt to prevent further bloodshed. Kim is having second thoughts about manipulating Danielle. Bob tries to lure Ferry into striking a deal with his South American contact.

Bob convinces Ferry and John to travel to France to meet his South American contact. Danielle makes Kim a dangerous offer. Bob wants to close the deal no matter what, but that means he will have to go head-to-head with John.

Bob does everything he can to keep the case afloat, making more and more enemies along the way. He still has one more card up his sleeve to catch Ferry, but he needs Kim's help to do it.

At Bob and Kim's bachelor party, Bob is finally able to convince Ferry to swap a large load of XTC for South American dope. But when their carefully laid-out plan goes wrong, the undercover agents have to risk everything to avoid ending up empty-handed.
