Based on the first of a trilogy by Tom Rob Smith and set in the Stalin era of the Soviet Union. The plot is about an idealistic pro-Stalin security officer who decides to investigate a series of child murders in a country where supposedly this sort of crime doesn't exist. The state would not hear of the existence of a child murderer let alone a serial killer. He gets demoted and exiled but decides, with just the help of his wife, to continue pursuing the case. 一部欧洲人演绎假装在苏联的日系悬疑推理片。原著中令人震撼和感动的情节被删去与修改了。对的这是一篇吐槽。这是一部被严重低估的电影！。这和我们有什么关系呢？。这不是一部悬疑片。“他们是被西方敌对势力和资质阶级毒害腐化受过训练然后潜入我们通过凶杀来搞破坏的”。短评写不下。老汤是OK的。叛国追凶。 故事发生在斯大林时代的前苏联，男主角Leo Demidov是一名苏联国家安全部(MGB)的特工，他尽忠职守、热爱自己的国家，充满理想主义。作为一名战斗英雄，Leo享受国家给予的特别待遇，不仅他自己一家住在莫斯科的豪宅区，他的父母也分到了很好的公寓。尽管也秘密逮捕和刑讯逼供，但Leo认为这都是为了国家利益。不过一桩儿童系列凶杀案改变了Leo的生活轨迹，政府不愿承认凶案的事实，一心想捉到凶手的Leo成为政府猜疑的目标，只有他的妻子始终站在他这一边……
