Hypnotist and magician David Cheishvili, trying to rescue his son from a petty criminal history, makes some concession to the investigator and helps to get the coveted signature in the testimony of a certain defendant. The hypnotist's abilities are put into use. The trick succeeds and the victim signs under the testimony, but the rules of the game are violated by the investigator himself.
