Sofia, the businessman’s wife, works at a bookshop out of boredom. One day, a boy—actually, a парень who looks like a bandit—attacks one of the customers. Without thinking long, Sofia steps in for the intelligent visitor, and he manages to escape. To her horror, “the bandit” turns out to be a detective from the criminal investigation department, and the helpless old man is a maniac called the Cannibal Ludoed, whom the police have been searching for for a long time. The would-be rescuer is made into “bait,” and a surveillance team is assigned to her. The maniac appears to Sofia from time to time and vanishes; he calls her by phone and even, having been in her apartment, leaves a note with a declaration of love. In short, the maniac gets closer and closer to Sofia, leaving new victims in his wake.
