Feature Length Story.
Set after The Green Death. After following the Doctor back to UNIT HQ from the village of Llanfairfach, the Brigadier's cure for the Doctor's two broken hearts is to apply liberal doses of his grandfather's famous malt whiskey. This remedy sets off a chain of events that catapults the Doctor and Brigadier into the scene of a railroad accident investigation, a ruthless robber baron of the Old West, and a mysterious poison for which there is no remedy. The death toll is mounting, the TARDIS is floating unpiloted through time, and it's up to the "two mysterious gentlemen from London" to solve the mystery, find the killer, or face an old fashioned lynch mob! Six Episodes.
