An extended sequence in which a man tortures a woman psychologically, physically and sexually. The woman is bound and restrained throughout and the man in question is in a position of absolute power and control over her. The man tortures the woman in order to make her confess her crimes against an unnamed 'State' but his ultimate aim is to break her down and make her fully compliant, eradicating her individuality and making her a mere number, 'NF713.

It takes place just after Stalin 2, introducing the story and continuing with the heroine from the point where she is sentenced to be locked up in a “medical” institute controlled by the StB and the Ministry of Defence of the then communist Czechoslovakia.

The film opens with some historical footage of the Stalin regime. Next we see Katerina, the unlucky culprit of the first Stalin film, being interrogated at Secret Police Headquarters. The interrogator says "like father, like daughter" and she is ordered to strip. That she weeps as she unwillingly removes her clothes adds to the delicious effect.
