Directed by Carl Jørgen Kiønig, this gripping Norwegian crime thriller is based on the best-selling novel by Anne Holt. The film introduces the sharp, fiercely independent police detective Hanne Wilhelmsen during a stifling summer heatwave in Oslo. The city is gripped by terror when a series of bizarre, highly violent crimes emerge: large pools of blood are discovered at various abandoned locations with no bodies in sight, accompanied by a string of unsolved missing persons cases. As Hanne digs into the cryptic clues, she uncovers a disturbing link to a systemic pattern of sexual violence, a grieving father seeking vigilante justice, and a cold-blooded serial rapist operating under the radar.
