It's election day and the Prime Minister has everything to gain, as long as Emilie's fate remains uncertain. Kamper is still haunted by personal demons, and issues of loyalty from within his own ranks rear their ugly heads once again. Meanwhile, as Lund and Borch start to look ahead, police are led to an undisclosed location in a last ditch attempt to find Emilie before it's too late. They are followed by a now dangerously tense Robert Zeuthen. Will the operation succeed in bringing the girl to safety?

Monday, November 3. Police detective Sarah Lund is about to leave her job in Copenhagen to move to Sweden. Troels Hartmann is gaining ground in his efforts to lead his party to power at city hall. Theis and Pernille Birk Larsen are the happy parents of three children. The discovery of the blood-stained belongings of a young girl prompts a police investigation that will change the lives of all involved.

Tuesday, November 4-Wednesday, November 5: Lund and Meyer track down the driver, who ends up injured in the hospital, but also supplies an alibi. They refocus their investigation on Nanna's school. When the story of the connection to his campaign breaks, Hartmann finds himself in media turmoil. The Birk Larsens try to cope with their loss as they arrange the funeral.

Wednesday, November 5-Thursday, November 6: The police investigate the crime scene they have found at Nanna's school and suspect her classmates Oliver and Jeppe of wrongdoing. Sarah Lund's fiancé shows up in Copenhagen, and she promises to leave for Sweden without delay. Meanwhile, Hartmann learns that a trusted employee has sent a suspicious email.

Friday, November 7-Saturday, November 8: Lund and Meyer investigate teacher Raman al Kemal's actions on the night of the murder. Hartmann learns of foul play at city hall, and his campaign is put under pressure when his opponent reveals Hartmann's ties with the suspect in a TV debate. On the day of Nanna's funeral, Lund is finally on her way to Sweden, and the appearance of one particular guest makes Nanna's father offer him a ride home.

Saturday, November 8-Sunday, November 9. Lund decides to stay in town to continue the investigation even though it puts her relationship with Bengt under strain. Rama is questioned as the main suspect. When Hartmann chooses not to suspend him, it puts his political position under threat.

Sunday, November 9-Monday, November 10. The police locate the place where Nanna was killed, and Rama is charged with the crime. Hartmann is fighting for his political life, but ends up making a tough choice. Meanwhile, Bengt is in a car accident on his way to Sweden, but tries to help Lund from his hospital bed. When the evidence is cast into doubt, Rama is released, but someone has other ideas.

Monday, November 10-Tuesday, November 11. Theis Birk Larsen's brutal punishment of Rama is interrupted by the police, and Theis is arrested. Lund and Meyer refocus their investigation on the car used by the murderer, knowing that if they do not make progress they might be taken off the case. As it becomes known that Rama is no longer a suspect, Hartmann shakes things up at city hall and relaunches his campaign.

Tuesday, November 11-Wednesday, November 12. Bengt leaves for Stockholm. Lund and Meyer are hindered in their investigation by a secretive boss, but Lund continues inquiries and is dismissed for her sins. Hartmann strikes a deal with higher powers in order to secure his bid for mayor, and a public debate is the scene of a change in political fortunes. Theis is released from prison, new secrets are uncovered about Nanna's last months, and in a last bid to forward the investigation, Lund unlocks the door to a new piece in the puzzle.

Sarah and Jan know who they are looking for but are puzzled by their superiors' reactions.

Sarah and Jan interrogate Troels, whose private information opens a new can of worms.

The spotlight of the police and media is now trained on Troels Hartmann, and he feels his political career is crumbling. Meanwhile strange things are going on at the town hall with fatal consequences.

Troels's political opponent Bremer wastes no time in taking advantage of his discomfort.

Sarah has walked into a life-threatening situation.

Sarah won't get on board when her superiors insist that Nanna's murder has been solved.

Lund and Meyer become convinced there is a link between Nanna's murder and a case that has remained unsolved for 15 years, and frantically try to find evidence. Meanwhile, Pernille and Theis are confused by the fact the case is far from closed, and Hartmann puts everything on the line in a bid to win the election.

Lund and Meyer get more than they bargained for when they visit an abandoned warehouse in their search for evidence. Meanwhile, a prime suspect disappears, and Hartmann struggles to get back into the political arena - but is contacted by a journalist whose efforts to dig up dirt have had some success. Theis and Pernille try to move on from the past 18 days' events and take their sons to see the new house.

Lund finds the odds stacked against her as the search for a missing suspect takes an unexpected turn, and Hartmann and Bremer take part in a dramatic, live TV debate amid a stream of revelations. Meanwhile, it seems something is amiss as Theis and Pernille prepare to move into their new house.

Lund is determined to catch Nanna's killer despite being taken off the case, and Hartmann is on a downward spiral - until he receives crucial information. Meanwhile, Pernille and Theis invite friends and family to Anton's birthday party - but there is a sinister twist to the evening in store.

A suspect is taken in for examination as the police try to find out more about the notebook they discovered, but things go less than smoothly. The prime minister and his close aids become the focus of police attention, as Karen is also found to be hiding a dangerous secret which could prove fatal for the government. Borch and Lund's trip to Jutland begins to have consequences. Robert Zeuthen intensifies the hunt for his daughter, despite coming under heavy pressure from the Zeeland board. Maja takes sides. A witness turns up who may have important information about Emilie.

Sarah Lund is held back in her attempts to make headway with the investigation, but at least the perpetrator finally has a face. Will he lead police and the Zeuthens to Emilie? Prime Minister Kamper is trying to clean up his circle as he attempts to find out what happened to his son. Suspicions arise about a trusted Zeeland figure as Robert Zeuthen considers drastic action.

The kidnapper continues to insist that he's seeking to recover a debt. If Lund is to save Emilie's life, it will be up to her to find out what the debt is and how it should be repaid. Following a request for Robert Zeuthen's life in exchange for Emile's, police set out to organise the exchange. Meanwhile, the integrity of a few high-ranking politicians is called into question, as Prime Minister Kamper takes a dramatic decision.

A new element turns out to play a role of great significance in the investigation. Borch and Lund have a hard time shaking off their Jutland experience, and their working relationship suffers as a result. Robert and Maja harbour hopes that Emilie may still be alive and Zeeland throw all their resources into tracking her down, as a secret is revealed from an unlikely source within the family. Police run checks on Ussing's movements over the last couple of years.

Denmark is the midst of a fiercely contested election race, set against the backdrop of the financial crisis. With ten days to go to the election, Detective Chief Inspector Sarah Lund prepares to celebrate her 25th year in the police force and looks forward to the prospect of a new job in the force. But her relative peace is shattered when body parts are found at Copenhagen dock only hours before a scheduled visit by the prime minister.

Following the kidnapping of Robert Zeuthen's daughter Emilie, Copenhagen Police put every effort into tracking down the perpetrator and finding the little girl. Meanwhile, the kidnapping has quickly become a hot potato in the election campaign and Prime Minister Kamper must deal with the fallout.
