Kirill (Nikita Volkov) has a great life as a very successful video game designer; he has lots of friends, loving parents and a beautiful girlfriend, not to mention a loyal dog. But one evening when he returns to his apartment, he finds a stranger there - a woman named Renata (Severija Janusauskaite) who insists that the apartment (and the dog) belongs to her. In trying to straighten the situation out, Kirill soon discovers that all of his documentation has somehow disappeared from official records, his boss doesn't know him and worse, neither do his friends or even his parents. He is now at the mercy of Renata, who instructs him to go to a tower, where he will serve as the customs officer, opening doors to other worlds. And he's very good at what he does.... This sketchy description barely scratches the surface of this film, which is full of gorgeous imagery (steampunk vehicles, graceful dirigibles and terrifying flying matryoshka dolls) and out-of-this-world fight scenes. Really fun stuff, if bewildering at times.
