A train crashes in the suburbs of Buenos Aires, leading forty-three people dead. A prayer card of Saint Expeditus, the patron saint of urgent matters, is left blowing above the wreckage. Hugo, a criminal on the run for murder, is also on the train. He seizes his chance to sneak out of the wreckage unsuspected, abandoning his possessions -- and, he hopes, his identity -- among bodies mangled beyond all recognition. The police suspect he's still alive, but are left scrambling to keep up as the media releases a barrage of misinformation and rumours as to his whereabouts. Whipping through the Buenos Aires mafia to the families affected by crime, the investigation uncovers the corrupt influences propping up power, and asks the ultimate question: will justice ever be served?
