Model Spy is an episode from the Captain Scarlet And The Mysterons television series.
Two models, eager to make their names publicised and internationally known, are killed in a dramatic staged railroad crash, while en route to Paris, and are rebuilt by the Mysterons, in an attempt to assassinate Andre Verdain owner of the "House of Verdain", a top modelling & fashion design company, which kept his real occupation as the controller of the European Area Intelligence Service a secret. Captains Scarlet and Blue, along with Angels Symphony and Destiny are assigned to act as French newspaper photographers and stunning, attractive models, in order to guard Verdain from any Mysteron attacks, but they are absolutely oblivious to the presence of the two female model doppelgangers.
