Private detective Tatyana Ivanova took up the investigation of a strange case - someone decided to disrupt the competition of young performers in the city. The attacker methodically gets rid of the participants. Doesn't kill, no. It simply deprives them of the opportunity to fight for victory. What is this: someone’s prank or the intrigues of envious people? Why are talented singers prevented from making themselves known? Yes... in show business sometimes things like that don’t happen. They might even kill you. Before things turn into serious trouble, Tatyana needs to hurry. Fortunately, she understands: artists are people too. And they, like everyone else, have their weaknesses. And Ivanova’s main rule: if you want to find a criminal, look for his weak point - it always works flawlessly!..
