The body of the young Rebecca Trolle, who had been missing for three years, is found on a construction site in Stockholm. During the investigation, it turns out that the student was working on a sensitive topic for her exam: The murder that the well-known composer Thea Aldrin allegedly committed to her husband Niels decades ago. The police investigation found: Rebecca thought Thea Aldrin was innocent. Did anyone want to stop the young woman doing her research? Rebecca had old video footage from the then “Cinerama” club, which included Spencer Lagergren, Fredrika's partner and father of her daughter. The video shows a murder of a young woman. The clique is suspected and the police are also looking for Spencer - which puts Fredrika in a predicament.
