"Doctor Who: The Creature From The Pit" - On the planet Chloris, metal is scarce, and without metal for tools, it is impossible to keep the planet's fecund jungle under control. When the TARDIS is forced to make an emergency landing on Chloris, the Doctor is captured by the power-hungry Lady Adrastra, who controls the very last metal mine on the planet, holding onto power through her Huntsmen and Wolfweeds. Romana is taken prisoner by rebel bandits, looking for some way of getting their hands on Adrastra's wealth. If K9 had feelings, he would have much to fear. Made of metal, he is a valuable commodity indeed. As if the situation were not bad enough, something is lurking in the pit of the last mine.
