Radio reporter Toivo Teräsvuori gets an idea for an experimental report using a hidden microphone, but he is reported as a madman talking to himself and is taken to the Houruniemi mental hospital. At the hospital, the volatile Toivo is considered insane, and even his wife Eila's testimony does not help the matter. Instead, Professor Piukka orders Toivo to undergo brain surgery.
