After his wife dies in a tragic train accident, the recently-deployed Markus must return home to his care for his teenage daughter. But when a survivor of the wrecked train surfaces claiming foul play, Markus begins to suspect his wife was murdered and embarks on a mission to find those responsible.

With tonal shifts as abrupt as its violence, this dark comedy is frequently as tense as it is witty. As the unlikely recruited muscle for three odd academics investigating a suspected assassination, Mads Mikkelsen’s military man burrows down a conspiracy rabbit hole to distract from his own grief.
