Detective Baldassarre spends his forced exile sorting criminal records. He gets a chance to return to the line of fire when two people, an aristocrat and a worker are struck by lightning inside a fancy mansion. The incident would be relegated to freak accidents, but Baldassare's attention is drawn to the strangeness of the events and he begins to investigate.
