Jazz musician and trumpeter Beno is originally Slovak, but has been living in Prague for a long time. As a true bohemian, he does not recognize any limitations in his personal or artistic life. He is devoted to jazz with body and soul and despises any form of pop music. That is why he rejects the lucrative offers of his girlfriend, the successful singer Gábina. He also successfully faces the pressure of his much younger girlfriend-to-be and her defiant mother. Beno often has to pay for his tricks, but he accepts this with open eyes. Beno is ably supported by his friend, saxophonist Emil, known as Rampouch.
