The Doctor kills the Myrka with an ultra violet light generator. Vorshak & Preston discover Nilson's treachery but he kills Maddox and escapes taking Tegan hostage. Turlough & Bulic are captured and imprisoned in the sleeping quarters by the Sea Devils. The Doctor rescues Tegan but Nilson is killed by the Sea Devils and the Doctor & Tegan captured.
Oh my word what an awful episode of Doctor Who. Lots of the Myrka, whose problems are well documented but far too much of the Sea Devils & Silurians waddling very slowly along corridors. The Sea Devils look a state: their head gear doesn't suit them, plus frequently it isn't on straight and their hand guns look like little hand held torches. And Ichtar says Excellent again for the third episode running. Are we sure this wasn't actually written for the Cybermen? At least they can move a bit faster! And as for Solow attempting to use partial arts on the Myrka.....
Three of the cast have prior Doctor Who form on their CV. Ingrid Pitt, Dr Solow, was Queen Galleia in The Time Monster as well as appearing in a host of Hammer Horror Films. Stuart Blake, the Silurian Scibus, was Zoldaz in State of Decay and the Commander in the previous story The Five Doctors. James Coombes , Paroli, would have been the Voice of Kraags in Shada and also voiced the Sentinel 7 spacestation in episode 1 of this serial.
Three more of the cast have obvious sci fi credits to their name. Ian McCulloch, the treacherous Nilson, was in Terry Nation's Survivors as Greg Preston. Tom Adams, Commander Vorshak, was in the UFO episode The Psychobombs as Captain Lauritzen. Finally Nitza Saul, Karina, was in the Star Cops episode A Double Life as Chamsya Assadi.
