After the recent death of his son, Detective Max Sorenson relocates to Oslo Homicide where he's teamed up with Detective Sander Holm. They're sent to a crime scene - four immigrant teenagers drowned in an abandoned swimming pool.
The identities of all five boys come to light. Turns out the missing fifth boy, Jabrill, was awaiting trial for the murder of a beautiful young Norwegian law student, Sophie Naess.
The murdered law student Sophie Naess turns out to have also been a high-class prostitute working with Karina Urdahl. The detectives locate Karina and her pimp Remi. As they wait to make the bust, the two men bond.
The discovered door in the woods is an entrance to a bomb shelter. But the detectives must wait for swat team Delta to make risk assessments before they can conduct a raid; it's frustrating to wait.
Sander and Max experience hallucinations that turn real; they're violent against Bo and Asha, respectively. Scrutiny over Sander's handling of Dalmar case escalates, while Asha begins to suspect Magnus is guilty of murdering Sophie Næss.
