A film based on a book by Jaroslav Kmenta tells the story of a mafioso who got rich by tax fraud of billions of crowns in transactions with petroleum products and who later tried to gain control of the state-owned petroleum concern. The main character is the gangster Radim Kraviec (Hynek Cermák). He was always capable of violence, but when his father is abducted and killed by a competing mafia, he is changed into a murdering monster.
After narrowly escaping arrest in Prague, Czech mobster Radim "Kácko" Kraviec flees first to Seychelles and then to South Africa where he continues with his criminal endeavours. However, his illicit activities cannot go unnoticed forever.
A humorously infused fairy tale about what happens when a dragon is not defeated by a brave prince but by an ordinary Janko. The joy of saving the princess does not last long, as the groom is to be a local village boy who, besides having patched clothes, also lacks good manners. The princess runs away to the real prince Egon, but finds out that it is not the royal title, but a good heart, that matters.
