While searching for a criminal, investigators find themselves in a series of dramatic and dangerous situations. The risk is even greater when the dangerous man is not being tracked by a professional team of criminal investigators, but by a private individual. This is the case of journalist Gavlas, who finds himself in a dangerous situation while performing his profession. Anonymous threatens him with death if he does not abandon his profession. Gavlas must deal not only with the problem of his personal attitude towards the principles of the journalistic profession, but above all he must uncover and neutralize a hidden adversary.

The honest and a bit naive director of a variety agency, Jožin Petránek, sits on the qualification committee that judges entertainers and performers of all kinds. The man firmly rejects any favouritism. But at work and at home, he's in for nothing but trouble. The rejected "artists" protest, and Jožin's wife Anna would like to promote her friend's daughter into show business. His new secretary Zuzana starts to seduce him. Petranek finally succumbs to the French chansonnier Madelaine. But Zuzana calls Mrs. Petrankova and she drives her husband away from the table and the bed. Eventually, Jozhin loses his position as director and becomes an ordinary stage recruiter. Now the real showbiz hype is just beginning for him...
