In the emotionally charged final season of this acclaimed crime thriller, British detective Karl Roebuck (Stephen Dillane, Game of Thrones) and French commander Elise Wassermann (Clémence Poésy, Tenet) take on a murderous couple with a nihilistic death wish—and ultimately face an impossible choice. "A heart-tugging plot and dazzling central performances…. An unmissable triumph" —The Guardian.
