Among the trio of inseparable friends, Shura Krushinskaya, a chemistry teacher at an evening school, was the most unlucky and least settled. Olga and her husband are well-known financiers in the city. Valeria has been a favorite of fate since childhood, and with the years, along with full prosperity, came also love for the charming husband.
The friends tried to change Shurka’s fate, looking for a good suitor, but Shurka was interested only in the school—her students and their problems. And when Krushinskaya got involved in Zhенька Zakharov’s affairs, whose mother and sister were killed by murderers, the targets of the criminals became the overactive teacher herself. And Shura’s life became unbearable.
But then—without exception—everything in the lives of the three friends changed, with the help of a private detective, Sergey Kotyatich, who was in love with Shura.
