As lost in this cold new world as her fellow immigrants, Lilly becomes the heart of this disenfranchised community in London, attempting to reunite people with their scattered families. But as her friend Amina discovers, Lilly's mission isn't purely altruistic and a passionate lost love affair is revealed between Lilly and Aziz (Yahya Abdul-Mateen II), an idealistic doctor.
