Mads, a police detective, is called out to investigate a body washed ashore near a wind farm. At first, it merely looks like an industrial accident, but the case implicates the upper echelons of Energreen - one of Denmark's most successful and leading energy companies. The CEO is charismatic Sander, and a young lawyer, Claudia, is working hard to advance in the company. Nicky, a former car thief and mechanic, has put his life of crime behind him for his girlfriend's sake, but his new colleague Bimse tempts Nicky with a chance to make a quick buck.

Claudia is given new responsibilities at Energreen, starting with a case about insider trading that could damage the company. Mads enlists help from Alf at the fraud squad to find a connection between the death at the wind farm and Alf's impression of Energreen as being a little too clever. At home, Mads is trying to keep his family and home running smoothly despite his wife's recent multiple sclerosis attack. Bimse and Nicky's car theft gives surprising results.

Mads and Alf pursue leads to Energreen's missing traders. Claudia is questioned, but is quickly summoned to Abu Dhabi by Sander. He and the rest of Energreen's management are attending an important energy conference to attract major investors. Amid the sparkling luxury of the desert state, Claudia witnesses a new and revealing aspect of Sander's fascinating world and how he operates. Nicky and Bimse are afraid of getting caught and bury the money they found in the BMW. But all that cash is tempting. What's the harm in spending just a little of it?

Mads and Alf interrogate Ulrik, the CFO of Energreen. But while Mads and Alf delve deeper into the company's secrets, serious developments are taking place in Mads's private life - Kristina has lied to her husband. At Energreen, the management is hard at work trying to streamline the company before going public. Claudia is sent to Thullander Industries, a subsidiary, to make cutbacks and ends up in a sticky situation. Bimse is in trouble with some debts, and Nicky promises to help him.

Mia is approached by a whistleblower and focuses her energy on finding out the truth about Energreen. Sander and Mr Christensen worry that Mia's findings could jeopardise their listing on the stock exchange, and they plan to stop her with Claudia's help. Mads and Alf follow one of Mia's leads to Energreen's research facility in Poland, and Mads is glad to get away from his chaotic home life. Jan wants to help Nicky and Bimse out with the Serbs and introduces them to Erik, their new accountant.

Despite Energreen's best attempts, Mia's article is published and puts the company on the spot as they try to find investors before going public. The article isn't Sander's only problem, since Nicky tries to blackmail him with the contents of the stolen iPad. Claudia is troubled with doubt about Sander. Mads and Alf are desperately looking for the whistleblower who was Mia's source.

Jens Kristian divulges Energreen's illegal setup to Mads and Alf, but it is not enough to prevent the company's big moment - the long-awaited listing on the stock exchange. Claudia sneaks away from Sander's big day. She is shocked by what her son Bertram has witnessed. Erik needs medical attention, but Nicky and Bimse do not dare take him to hospital. Mads makes a decision about his home life.

The minister of justice pressures the fraud squad to close the case against Energreen. However, what Jens Kristian tells them incriminates Claudia more than Sander. Bimse's emotions put him and Nicky on a collision course.

Alf is guilt-ridden about Mia, but he snaps out of his self-pity when Mads makes an amazing discovery. Not only does Energreen have major accounting discrepancies, its coffers are also empty, and they can use this to their advantage. Claudia has reached the same conclusion, but Sander insists on continuing his dangerous game and asks her to throw a spanner in the works and ruin the fraud squad's plans. Sander's henchman finds out where Nicky and Bimse got all their money and insists on getting it back - the Swede isn't a man you refuse.

The media are shocked by Energreen's announcement, and Mads and Alf are busy searching for evidence to use against them. Claudia is at a crossroads in her life as she realises how serious the consequences could be for her. Nicky and Bimse hide from the Swede. Mads helps Kristina who is back in hospital, just like in 'the old days'.
