Roger Quain, die twee zwarte panters die in de dierentuin geboren zijn begeleidt in de trein van Milaan naar Parijs, gaat akkoord met het helpen van Catherine Ullven, een geheim agente uit het Westen. Roger moet een microfilm van Catherine verbergen in de halsband van één van de dieren. Maar wanneer de trein in de Zwitserse Alpen ontspoort, ontsnappen de panters. Drie geheim agenten van de vijand jagen nu op de beide panters, maar ook op Catherine en Roger.
Nee, helaas is Spy Hunt nog niet beschikbaar op Netflix in Nederland.
