私家侦探Tommy Akhtar （里兹·阿迈德）在追查失踪俄国妓女的过程中发掘出一连串暗黑秘密，也牵扯出了关于自己和伦敦这座城市的不堪真相。这部犯罪悬疑电影根据Patrick Neate的小说改编，由BBC和BFI联合出品。 Leah, 10, lives in a large vicarage, full of lost souls and the needy. In the day the house is bustling with people; at night it is dark, empty, a space for Leah's nightmares to creep into. A small, nightly visitor brings Leah comfort, but soon she will realise that her little visitor offers knowledge that might be very, very dangerous.
