A father and his teenage son travel to Berlin. The boy has never met his mother who is in hospital with a coma. The father is confronted by his uncertain past. Both are unsettled by the winter gloom in the unfamiliar big city, and by the hostile environment of the hospital. The mother's flat where both are lodging is equally unwelcoming. They meet a mysterious and beautiful woman there, the mother's flat mate. While the boy explores the city, the father waits for the mother to recover.
