The Tardis is desperately short of Zeiton 7 ore to power its engines, and the Doctor and Peri know Varos is the only place that they may find it. But soon they become involved in the deadly politics of the planet, and the machinations of the sinister Sil, a slug-like alien who wants the price of Zeiton 7 lowered and the Doctor - along with the governor of Varos - out of the way for good.
