1944. Stockholm. In an area with a bad reputation, a brutal murder is committed. One of the first to arrive at the crime scene is Elsi Svenns, a young girl who has recently joined the police force. The killer doesn’t hurry to run from the authorities, and when Elsi gets in his way, her fate is already decided…
Thirty years later, Britt-Marie Udin—one of the first women detectives in Sweden—begins investigating a tangled case. From the crime scene, horror seizes her: everything is too much like the nightmare of her past. Years ago, in these slums, nicknamed the Bog, her mother died. The criminal remained faithful to his style in everything. Only this time, the victim survived.
Her colleagues don’t take Britt-Marie seriously, but she has a kind of strength that must be reckoned with—and it seems she’s about to get to the truth. Yet her persistence turns out to be not enough to confront the ruthless killer. The criminal slips away—and with him Britt-Marie disappears.
In the 1980s, her mysterious disappearance begins to raise questions. It seems the so-called Bog killer has reminded everyone of himself again. Another murder—after all these years. The police turn to Hanne, a profiler, hoping she will help them get a lead on the killer. But everything is in vain—the killer is elusive.
And now it’s 2019. The case is taken up by Malin Brundin. The burden of responsibility lies on her shoulders—she’s accountable to the victims of the Bog killer.
Because for all those years, women who were fighting to claim their place in a world dominated by men have, alone, been hunting a shadow. Will the killer get away again this time?
