Jan Michelsen comes across a 10-year-old case from the same neighbourhood where a 17-year-old girl has gone missing on her way home from a party.

Jan and Louise's investigation into Natasha's murder leads them to suspect Anders Kjeldsen; Emma attempts to comfort a traumatised Julie.

Jan and Louise come across an unsolved murder case in Sweden that is similar to Natasha's; on a farm that Anders Kjeldsen stayed at as a child, the police make a terrible discovery.

Louise realises that Anders Kjeldsen must have a partner in crime; Emma attempts to convince Stine to help her to escape in the basement.

Jan and Louise discover a dress that belongs to Natasha; Anders attempts to kidnap another woman; Stine Velin attends her big brother Mikkel's 40th birthday party and shares a family secret.

The identification of the third victim from the farm is made possible from the public appeal for information on Anders Kjeldsen; Louise believes that he has a female accomplice.
