František Kotleta's novel is set on Christmas Day 2107 in Prague - a gigantic megapolis. The Czech Republic, after the war with Poland over Silesia, is falling apart. Prague, dominated by the owners of the most powerful companies, has fortified themselves against the rest of the world. Everything that the city's inhabitants need is produced in Prague laboratories or factories, and what happens outside the borders of Prague City, nobody cares.

The city has enough problems of its own. Like the cult of cyber witches, which penetrates deep into the hearts of the inhabitants of the city while witches are being killed. Their protection will be provided by a Czech-Polish war veteran, a former Vachten policeman. This mission will take him to the riches of the top floors of skyscrapers and the decayed underworld (where you can always earn extra in the underworld by transplanting yourself three penises).
