The modern detective is investigating the dubious crime of the Duke Bluebeard: having acquired another wife, the duke soon killed her, but before that he had an incredibly blue beard. And were his unhappy victims really so innocent? The detective is going to investigate this case, calling his wife on the radio from his car on the road. Not believing that the husband is delayed at work and suspecting him of infidelity, the jealous wife demands that he immediately go home, threatening, otherwise, a divorce.
