Danila Chetkov is a detective in the Ethnic Criminal Activity Department. He knows everything that's going on in 'Chinese' Moscow. Nothing happens in the black market without him knowing about it. One day, Danila meets Yong, a Chinese who's come to Moscow to find his daughter. Danila investigates the Chinese 'mirror-world' in Moscow to help Yong and gradually changes his worldview. When Danila almost loses his son, he realises that there's nothing more important than honesty and true friendship. And he has a true friend in Yong.
