The TARDIS materializes on a planet where the age of prosperity comes
often, and precious jewels line the streets like litter. Overseeing the
citizens is the bombastic Captain, half human and half machine. Lurking
in shadows are the Mentiads, mysterious cowled figures who set their
sights on certain individuals and claim them for their own. As the
Doctor, Romana, and K9 become entangled in local events they are caught
between the apparently insane Captain and apparently sinister Mentiads.
But then the Doctor makes a terrible discovery beneath the surface of
the planet, and realizes the true nature of the Captain's operations.
Soon yet another planet comes under threat from the Captain, one which
the Doctor knows well: Earth. Can he manage to save it from a terrible
fate? John Leeson narrates this classic full-cast TV adventure, written
by Douglas Adams (The Hitchhiker's Guide to the Galaxy), and in a
special bonus interview he recalls his time as the Voice of K9 in the
BBC TV series. Also included are color PDF files of the original TV
camera scripts.
