Plot

Season 1 – In August 1990, the sadistic murder of a pregnant woman is committed on the island of Nordkoster, western Sweden. The victim is buried alive in the sand, so that the rising tide slowly drowns her. In June 2015, the murder, known as the Beach Case remains unsolved. Olivia Rönning, a trainee at the Stockholm Police Academy, is assigned the cold case for a summer project. Upon discovering that her late father worked on the original case, Olivia becomes obsessed with solving the murder. She searches for the lead investigator Tom Stilton, who has since become homeless and does not want to be reminded of his old life. Horrifying videos show up on the Internet in which other homeless people are brutally attacked including a friend of Tom's. Eventually Tom helps Olivia to investigate the murder. Along the way they are helped by Tom's former colleague, Mette Olsäter and their mutual friend Abbas el Fassi. They are thwarted by Rune Forss, a corrupt policeman and by Jackie Berglund, a former prostitute, madame and current store owner.
