with markus�*s teenage daughter, mathilde, who was on the train with her mum, struggling to find comfort or common ground with her dad. but instead, the film turns into something completely different — first, a paranoid conspiracy thriller as the disconsolate algorithm expert who fatally gave emma his seat convinces markus that his wife's death on the same train as a biker gang trial witness could not have been a coincidence — and then, as an increasingly—crazed black comedy. as markus and three misfit geeks wreak murderous vengeance on the supposed of killers while pretending, for the sake of mathilde, to be experimental grief therapists. if that sounds completely nuts, it's because, well, it's completely nuts, veering between action, drama, socio—political satire, and three stooges slapstick comedy not only between scenes, but sometimes right in the middle of a sentence.
