Along with a succession of companions, The Doctor faces a variety of foes while working to save civilizations, help ordinary people, and right many wrongs.
Dick and Mandy, a young working class couple, move into a council house in Canterbury, and find Mr. Butcher, one of their former teachers, living next door.

While taking in the sights of Paris in 1979, the Doctor and Romana sense that someone is tampering with time. Who is the mysterious Count Scarlioni? Why does he seem to have counterparts scattered through time? And just how many copies of the Mona Lisa did Leonardo da Vinci paint?
