The Killing

On what is supposed to be detective Sarah Linden's last day of work in the homicide department, she gets a disturbing dispatch.

Theis and Pernille's worst fear comes to pass when their 19-year-old daughter is found abused and killed; Sarah postpones her move to Sweden to investigate.

New and important clues turn up at Nanna's high school; Troels is experiencing problems as confidential information is leaked.

Sarah and Jan locate a room in the high school's basement with some disturbing evidence left behind; the information leak appears to affect Troels's political career.

Sarah realises that Nanna's friend, Lisa, was involved in more events at the high school party than she had let on; Pernille deals with her grief in her own way, while Theis struggles to cope.

Just as Jan starts to think he is in charge of the investigation, Sarah returns; Pernille falls apart because the police seem unable to prove anything.
