Unit One Season 2

A young boy is kidnapped on his 9th birthday. The team discovers him alive and well, but getting him back to his mother is not simple. Ulf and Kirsten take a trip to London.

A lawyer with a history of getting defendants to retract confessions uses the technique to exonerate the perpetrator of a crime that the team previously investigated. Then the lawyer and his family are threatened by an unknown attacker and the team is called in to protect him.

The owner of a chocolate factory is found murdered. Did his murder have something to do with his appetite for young women and kinky sex, or is there something else at play?

A woman dies in a house fire. Her 8 year old daughter fights for her life in hospital. Was the fire an accident or arson?

Local police overhears a shooting. A teenage girl comes running against them yelling "They're gonna kill me, they're gonna kill me!". The female police officer finds the body of Irana and Fashad Adavi in the apartment of Osmand and Leyla Güre. The reason for the murder is believed to be a matter of honour according to Osmand as he explains that Fashad supposedly has raped Yasemin, the daughter of Osmand and Leyla. The son, Dennis, supposedly shoots Fashad as he refuses to marry Yasemin. In questioning, Dennis fails to reload the pistol and is therefore not the murderer. Yasemin then claims she shot the victims. In a gynaecological examination, Yasemin proves to be a virgin. As the gynaecologist talks with Dahl, Yasemin escapes and, according to her home room teacher, hides in a botanical facility. The teacher explains that Osmand has sexually abused his daughter anally for years. IP finds the girl in time, as her father is trying to kill her with a piece of glass. In questioning, Yasemin explains that Fashad found out about her father and tried to force through a wedding with Osmand, who then kills her.

The body of the 10-year-old is found in a stream in the woods just outside of Hellebæk. No boy of the description is missing. La Cour dreams of a bag that is found at the harbour and has exactly the same interior as in La Cours dream. A social licence from the bag reveals the boy to be Martin Simonsen. DNA samples proves that the killer earlier has murdered a young boy. La Cour talks with a conductor from Odense, Claus Munk Andersen, who claims he didn't see the boy. But through a vision and investigation of other witnesses, Andersen is taken into custody. A DNA sample proves him to be the killer, but when the police moves out to arrest him, they find him hanged in his house and La Cour's fingerprints all over the place.

La Cour is taken into custody and is ordered home to Copenhagen. In the mean time, the investigation team contacts Karin, the sister of Andersen who tells them that the man that visited Andersen the night he was killed and had sexual intercourse with him probably is Sonny, a local male prostitute. Fischer is sent to the dumpster, where he finds a trash bag that contains Andersen's diary that contains information about the murdered boys and Cliff "Sonny" Jensen, whom Andersen raised into prostitution and lent to his friends. La Cour notices some ash buds and remembers what happened at Andersen's, paying Ulrik Gregersen, Andersen's brother-in-law a visit. He follows him to the dumpster where he arrests him and discovers that the trash bags he dumped there contained the body of Sonny.
