Rosa Ibragimova, having gone on tour with a dance group to Turkey, found herself a powerless slave in a terrible brothel... But she, the only one of all, managed to survive and get home. Fearing persecution, Rosa and her mother decide to flee their hometown, but on the eve of their departure they are killed. During the investigation, operatives discover a mysterious note that Rosa hid under her pillow and which not only did not clarify the circumstances of the brutal murder, but also added even more questions. Who was the note addressed to? What is in it - a warning or a cry for help? Back then, no one had imagined that this message would turn out to be a lead to a gang of slave traders in the twenty-first century...
