After assembling a gang of misfits, Carl chooses his first case – the disappearance of a public servant four years ago. 

Taking to social media, viewers hailed the show as "brilliant" and were "hooked" from the first episode. 

One person wrote: "Damn I've ended up binge watching Dept Q because I need to know what happened," while another added: "Leave it to the Brits to give a top-notch detective show. Hooked from start to finish, with very interesting characters."

Upon his return to work, Carl is assigned to lead a new cold case unit: Dept. Q. 

The synopsis continues: "The department is a PR stunt, there to distract the public from the failures of an under-resourced, failing police force that is glad to see the back of him. But more by accident than design, Carl starts to build a gang of waifs and strays who have everything to prove.
