Set in Sweden where young women have been turning up dead in a field of asphodel flowers over the course of 12 months, it centers on New York Detective Tommy Conley (Dominic Monaghan) who, through a special dispensation from the NYPD, is permitted to observe and advise the Stockholm PD. There, he is paired with veteran homicide detective Mikael Eklund (Michael Nyqvist), a by-the-book Swedish nationalist with an aversion to America’s grab-and-go culture. Both hate each other but have to learn to work together to stop the killings.
