The Ronov castle has been changed into a hotel, offering stylish facilities to its guests: weddings in the torture chamber, a Black Lancer kidnapping brides, a night's lodging in a family tomb etc. The reformed petty swindler Felix Pacínek (Bohumil Smída) runs the hotel. The business is far from thriving; the place is half-empty, and the jazz band Skeleton, together with their singer Zuzanka (Jaroslava Obermaierová), decide to leave. Nobody in the hotel has any idea that the band is in fact a gang of thieves who have just robbed the Prague State Bank, taking two million crowns from its vaults.
