Patrick Bluett is searching for a new life in the low light of a Copenhagen winter. Divorced and navigating the rocky relationship with his grown-up, nest-flown children, Bluett spends his days listening to John Coltrane''s majestic jazz symphony A Love Supreme and gazing out at the frozen streets, a desolate landscape that somehow matches his reflection in the window.

His nights, however, are a little different. Walking unsteadily across the cobblestones, he moves between the neon-tinted bars and clubs of his adopted home, talking whiskey, women and the world with the other lost souls of Copenhagen, those who only seem to come out at night. But when he befriends a neighbour, a man in similar circumstances, the apartment across the hall reveals some strange secrets and Bluett realises how little he really knows of the darkness of the city.
