A young girl was found murdered in a hotel room. Judging by the handwriting, this is the work of a maniac - "Hotel Chekatilo" Konstantin Revenchuk. But he is in a colony, serving time for five similar murders. Georgy and Irina understand: either Revenchuk has an imitator, or someone is trying to work to justify the maniac. It becomes known that the deceased often visited a lesbian club. The next visit was just before her death, and witnesses recall that that evening the girl met some unknown lady and left with her.
