Fembots, swashbuckling and a random Sasquatch. Plus everyone may be an android and we just never find out. What’s not to like about this serial?
The Fourth Doctor and Romana (I) head to the planet Tara to collect the fourth segment of the Key To Time. No problemo, says Romana and casually picks it up while Doc lets a gadget do his fishing for him. Then a Sasquatch we’ll never see again suddenly lumbers towards her, fuelled by a thirst for hugs and blood. Fortunately, she’s rescued by Count Grendel. Unfortunately, he’s a power-hungry, Iago-inspired ass-hat.
Grendel mistakes her for an android lookalike of the princess he’s already keeping locked up in his dungeon, and steals Romana away, and the Key segment along with her. Meanwhile, The Doctor is apprehended by Prince Reinhart’s men, and embroiled in a plot involving android doppelgangers, at least two bids for the throne and a heck of a lot of swashbuckling.
