Norskov is a town fighting for survival. Mayor Martin Kierkegaard is trying to rescue the city's future, but drugs are a problem among the youth. Police superintendent Tom Noack returns home to help Martin clean up Norskov's drug culture.

Diana's tragic death brings Tom closer to her brother, his old friend Casper 'Bondy' Bondesen, who now has to bury his sister. Oliver is angry and neither Bondy nor Tom can any luck approaching him. A simple mistake puts Martin's visionary project for a climate-friendly harbour at risk, and this time he is up against the greed of local money men. Tom's investigation reveals that Diana was together with a drug dealer in Norskov shortly before she died and that the cocaine that put the 15-year-old girl into a coma was uncut and particularly potent; Tom sees a connection.

Oliver has filled his apartment with old friends, but the void after Diana's death is still felt. He keeps wondering who his father is. He is having a hard time keeping things together, but Tom is committed to helping him. Thanks to Bondy's assistance, Martin's harbour project is back on track, and Martin repays his debt with a very good deal. At the police station, Oliver is cleared of all suspicion. At the same time, Tom's investigation reveals that an acquaintance of the drug dealer has moved to town. After a raid, Tom finds indications that more of the dangerous cocaine could be on its way to Norskov.

Tom and his team are investigating the suspected cocaine smugglers, and they get a couple of breaks in the case. Meanwhile, Tom's knowledge of a big secret puts him in a bind - both with Oliver, for whom he has been designated contact person, and with his sister Jackie. Martin and Jackie's marriage might be at stake after the past haunts them, and as the Danish Minister for Education visits Norskov to give the green light to Martin's plans, the temperature between Jackie and Martin is ice-cold. Meanwhile, Tom's surveillance reveals that this case may reach much farther than he had first believed.

Martin reveals his secret to Oliver. Getting a month to investigate, Tom and his team choose to go after the cocaine kingpin. Martin is a success and the town attends the groundbreaking. Meanwhile, Tom sees something he wishes he hadn't.

The story of Oliver's real father hits the front pages. Jackie is hit hard as the adoption is halted. Oliver is in the finals, but is struggling outside of the rink. Tom believes the kingpin might be someone everybody knows in town.

Oliver is sick of school and gets an apprenticeship at Bondesen Byg. Martin is living by himself, and things are not better at the office. Tom's investigation is falling apart, but an interesting wiretap provides a chance to crack the case.

Bondy provides Martin with some shady help, which drives Jackie farther away. A disturbing piece of information makes Oliver lose his head, with potentially damaging consequences to follow. Tom's investigation is starting to yield results.

The coke is on its way and Tom is waiting for the right time to strike. Martin finally launches the wave energy facility, and Jackie has to decide where to stand. Oliver's suspicion is increasing, and decides to tell Tom of his discoveries.

Martin must resign as mayor, but at home things are better. Jackie is back, and Oliver has agreed to move in. But a dark secret comes to light, which leaves Oliver devastated.
