Plot synopsis: Láďa is always joking. Petr has his own incomprehensible dictionary. Jana seeks a partner via a dating service. They are linked through their joy in music and their involvement in the group founded more than 20 years ago by bandmaster Šimon Ornest. Strictly, almost despotically, without pity but with great energy and understanding, he not only leads his musicians to a place on the music scene but is also their support and friend.
