The film, which opens with students arriving at a police academy, is a crazy comedy that is more a series of zany episodes and jokes than a coherent story. They are linked by a simple plot in which the commander of the police academy, Major Maisner, searches among his recruits for an alleged FBI spy and, after a not-so-subtle practical joke, gets into a dispute with his subordinate, a dispute that ends in a genuine bank robbery.

It all begins at Prague Airport, where American agents have brought Major Maisner, who has been expelled from the United States, in handcuffs. He returns to his place of work, the Central Police Academy, despite having been demoted to lieutenant for his "performance" and his position as academy commander having been taken over by the newly promoted Captain Hrubec. Maisner meets his former students, who now teach at the school. They all welcome him enthusiastically and receive gifts from him. While psychologist Kudláková, who is attracted to commanding types, has lost interest in the demoted Maisner and is now passionately in love with Hrubec, Boženka Vinklářová, who has broken up with the gypsy Štefan and now teaches dactyloscopy at the school, focuses her attention on him. Maisner recounts how he jumped off a skyscraper in America to defend himself against Simona Ptáčková's advances.

Thirty-five-year-old bachelor Jiří Šafránek is a train dispatcher, an amateur actor rehearsing the role of Hamlet, and the proud owner of a 1960 Stadion 22 moped. Because of the blue color of his beloved motorcycle, the police call Jiří the Blue Dragon. Jiří still lives with his mother, who finds it difficult to tolerate his escapades. Like Prince Hamlet, Jiří talks to his father's ghost. In addition, he is always running late and shortens his journey from work to theater rehearsals by taking a footbridge where motorcycles are prohibited. One day, he almost collides with a girl named Adina coming in the opposite direction. This marks the beginning of a relationship that will disrupt not only Jiří's coexistence with his mother, but also the preparations for the premiere of Hamlet itself.

The unit specializes in the investigation of serial murders and is led by Van der Bijl, a former murder and robbery detective who gained fame for his handling of several high-profile cases. Each episode focuses on a serial killer. The main character, Colonel Piet van der Bijl, also known as Die Byl, is loosely modeled on the famous ex-detective Piet Byleveld.
