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.
