Two young composers offer their operetta in vain - it is rejected before anyone reads it. By a coincidence, when its text ends up in the wrong briefcase, it ends up with a popular singer who, on the contrary, likes it very much, but has no idea who wrote the play... The search for the authors, personality confusion and budding love become the main plot elements of this pleasantly naive film, where there is constant singing.
