The Doctor and K9 have a Time Lady forced upon them and are sent on a quest for some lumps of perspex.

They find the first on a parky planet but, before they can get their hands on it, they have to contend with a couple of conmen, a whack job warlord, a rubbery reptile and a mad old dear with antlers.
