There’s a tragic train crash in Denmark, and one of the survivors, a true statistician, sees the connections and refuses to believe this was an incident. His friends help him with face-recognition software, and it identifies a suspect. They have to take the matter in their hands because the officials see the bunch as loony misfits, and ignore the research. The husband of one of the victims, a capable ex-soldier, joins the band, and then the suspect waves a gun at him. This is when the story starts getting interesting! I’m still surprised this Nordic comedy seems somewhat realistic, but this is not a bad thing, right?
