The Doctor, Vicki and Steve arrive in England in 1066 and are pitted against Saxon logic, brutal Vikings and a fellow time traveller.
It transpires that Steven (of ‘The Chase’ fame) stowed away aboard the TARDIS, so at least The Doctor won’t need to deal with Vicki on his own. The Stevemeister refuses to believe that they can travel through both space and time, whereupon Doc does what he claimed incapable of doing for Barbara and Ian, namely, take them to England. Alas, it’s the year 1066 and the Battle of Hastings is just around the corner, as are some weirdly trusting Saxons and some vicious and ill-coiffed Vikings.
That’s not all, though. Also present is a Meddling Monk, who goes by ‘Father’, has an electric toaster and isn’t really human. In fact, he’s a fellow Timelord. Which is pretty awesome, since this is the first time we encounter anyone from Gallifrey who is neither The Doctor nor Susan.
