Minneapolis, Minnesota, 2016. When a small-time criminal and gun dealer is shot down in the street, all signs point to Tomas Gomez, a quiet man with a mysterious past --- and deep connections to a notorious gang --- who has seemingly vanished into thin air. Other murders soon follow. Meanwhile, Bob Oz, a down-and-out suspended police officer, becomes fascinated by the case: he is obsessed with the notion of hunting down a serial killer who only he can understand. Minneapolis, Minnesota, 2022. An enigmatic Norwegian man with ties to Minneapolis --- a self-described crime writer --- has traveled to the United States to research the Gomez case, in the hopes of writing a book about it.
