Ulyana Sinitsyna is a young, intelligent woman. She works at Moscow State University’s Department of Psychology. The heroine wants to defend her doctoral dissertation, which is based on a new, previously completely unknown «graphic» method. The university committee considers this method unscientific and impractical. The young woman then quits and goes to work for the police. There she meets Major Igor Levin. His colleagues mock the somewhat peculiar girl who left a prestigious university for an ordinary department. But the very first investigations make everyone believe in the method’s effectiveness. Levin is investigating the disappearance of a ballerina. Soon, her mutilated body is found. Having studied the nature of the wounds, Sinitsyna concludes that she is far from the first victim and that a serial killer is operating in the city. At first, the management did not take this idea seriously, but girls continued to disappear. Meanwhile, Ulyana was not well liked in the department because of her astonishing successes. Will the heroine be able to withstand the pressure from her colleagues and catch the dangerous criminal?
