Pletnev and Turetsky, after a little spree, stayed in Novorossiysk. But professional investigators do not remain idle. Pletnev is looking for the killer of the prostitute Gali, whom he knew for only a few hours, but during this time he realized that she was in danger. He even managed to be a suspect. Therefore, he considers it a matter of honor to find the real killer. Former bullet shooting champion Gushchina, who ten years ago was unfairly accused of negligent homicide and sentenced to three years, comes to Turetsky from Stavropol. Years later, she realizes that someone wants to interfere with her new successful life by bringing to light information that discredits her about her former criminal record. She asks Turetsky to investigate an old case in order to restore her good name. Turetsky gets down to business and soon understands who the real killer is and why Gushchina was convicted instead of him.
