The Doctor is having slight problems with his two companions: K-9 seems to have, somehow, caught laryngitis. Romana is somewhere in the TARDIS, and when she appears she has regenerated into the same body as Princess Astra. The Doctor tells her to try again, but she later settles on the Princess Astra body.
The TARDIS materialises on a radioactive planet. The Doctor and Romana take the necessary precautions and venture outside. They find sections of concrete, and judging by the vibrations there is some serious drilling going on somewhere.
Looking inside the remains of a city the Doctor becomes trapped by a pillar, and Romana goes back to the TARDIS for K-9. Meanwhile the stone pillar is effortlessly lifted off the Doctor by what appears to be an ordinary man.
The Doctor learns that he has been rescued by the Movellans, who are here to stop the Daleks from getting to Davros. Both sides are robotic and logical, and can easily anticipate each others moves as each move is logical. If the Daleks rescue Davros he could introduce random elements giving the Daleks the advantage.
At the same time the Movellans realise that if they use the Doctor the advantage can be theirs. The Doctor realises that the Movellans are no better than the Daleks. With the aid of a human captive the Doctor manages to prevent the Movellans from destroying Skaro, and also manages to defeat the Daleks. Davros is taken prisoner by the Humans.
