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.
Unfortunately the movie Double Murder is not yet available on HBO Max.
