关于苏联契卡与伟大卫国战争结束后留在我们领土上的德国特工的斗争。 1947年。“阿尔泰克”（Artek，苏联著名的夏令营）首次决定举办国际更替活动（一种夏令营活动）。为了破坏这一盛大的节日，间谍们决定毒害孩子们。但他们的主要目标是暗杀斯大林，他们正等着在更替活动开幕式上见到他。只有最敏锐的契卡（苏联国家安全机构）特工才能揭露这些外国间谍。

An animated adventure that follows the adventures of a little girl and her friends as they look for a magic nut.

Policeman Pavel Kravtsov is a rather strange man. If he has to handcuff someone, he apologizes and asks if he is pressing. He is ambitious but honest; he is young but thoughtful. With such inclinations, you can't really make a career in the city police. So a city man, senior Lieutenant Kravtsov, gets through to the remote village of Anisovka by an ordinary district police officer.
