Plot of the series
After a traumatic shooting that left his partner paralyzed, DCI Carl Morck is sent to a cold case unit in Dept. Q. At first, it looks like the department is just a publicity stunt, but Morck quickly realizes that it could lead to the discovery of dark, long-buried secrets.
Morck looks into the strange disappearance of prosecutor Merritt Lingard with his new team, which includes the unusual Detective Rose and a regular guy, Akram Salim. Merritt disappeared 4 years ago after losing a well-known case against Graham Finch, who was accused of killing his wife.
There were threats around the case, and Merritt was last seen on a ferry going between Edinburgh and Mhòr. Akram is sure she is still alive, and his guess is proven when the team finds Merritt locked up in a hyperbaric chamber by people who want her to make up for a mistake she made in the past.
Carl and his team find out that Merritt's relationship with her brother William is tense. William was the last person to see her. They also begin to suspect that Graham Finch might have something to do with her disappearance. At the same time, Carl is dealing with the effects of the shooting that left his partner paralyzed.
The investigation into Merritt's disappearance eventually reveals some upsetting facts. This includes a painful part of her childhood in which she was hurt during a theft that was supposed to be fun for the family. Ailsa and Lyle Jennings, who held William captive, blame Merritt for the trauma he caused.
In the final episodes, Carl and Akram find the Jennings' hideout and get Merritt out of danger. They can't bring Finch to justice for killing his wife, though, because he was already found not guilty. Merritt is saved at the end of the season, and there is a hint that Carl's journey to solve cold cases is just getting started.
Dept. Q is available for streaming on Netflix.
