A chilling documentary series that unravels a series of brutal sexual assaults in Stockholm from 2018 to 2020. At first, police struggle to find a common link between the attacks, which occur near popular beaches. But when a young woman is violently assaulted in 2020, filmed by her attacker, investigators realise they’re dealing with a serial rapist.

DNA evidence links the assault to a prior attack, leading police to a terrifying realisation: the perpetrator is a respected preacher in a small community, caught in a personal battle with his dark urges. As the investigation intensifies, both the victims' harrowing experiences and the twisted psychology of the predator are explored. In a race against time, the police must stop the predator before he strikes again.
