After their first spectacular success in
Department Q: The Keeper of Lost Causes (2013), deeply flawed but brilliant Detective Carl Mørck and his perceptive assistant Assad gain an unwanted new assistant: the intelligent, strong-willed secretary, Rose Knudsen. Before long, another cold case lands on his desk, and, naturally intrigued, Mørck decides to investigate a brutal brother-and-sister murder that occurred two decades earlier. But, as the team digs deeper and deeper into an incident that dates back to 1994, they can't shake the feeling that something doesn't add up, suspecting that Kimmie, a half-mad vagabond, knows more than she is letting on. As a result, some influential and dangerous individuals, all former members of an elite boarding school, want their dark past to remain buried, hell-bent on silencing Kimmie for good. Can Department Q shed light on the tangled mystery of the Absent One?
