Gentleman-oplichter Jerico (Patrick Macnee) en zijn assistent jagen op de vermaarde Gemini-diamant die in het bezit is van een doortrapte schurk-miljonair (Herbert Lom) op Malta. Maar waar is de èchte steen? Jerico gaat koortsachtig op zoek. Slaagt hij erin de diamant te vinden?
Nee, helaas is Mister Jerico nog niet beschikbaar op Netflix in Nederland.
