Whilst sightseeing in Paris, 1979, the physician and Romana see some unexplained temporal disturbances. Whenever a visit to the Louvre lands them in hot water, they realise a certain Count Scarlioni understands more about advanced technology when compared to a 20th Century Parisian should. With Uk detective Duggan in tow, enough time tourists become embroiled in an audacious plot to grab the Mona Lisa and sell it within the open up market. Not just that, but Rely Scarlioni seems to have more da Vinci masterpieces at his removal – each one apparently genuine. What period experiment is certainly Scarlioni forcing a genius teacher to undertake? What’s behind his suave persona, and what exactly are his plans for not merely Paris but the entire world? The Doctor and his friends must uncover the answers before period itself runs out. Lalla Ward narrates this classic TV experience, and in an exclusive reward interview she recalls her period as Romana in the BBC Television series.
