The series tells the story of the heroine (played by Margarita Levieva) who is on vacation in Europe with her daughter. At this time, the appearance of the CIA forces her to face her long-hidden KGB identity. In the past, Russia conducted secret experiments that enabled some KGB to have special powers, and a series of deaths related to this ability made the heroine unable to hide anymore, but the price of dealing with this murderer is that she may lose her family and her new life.
