The TARDIS brings the Doctor and Sarah to Exxilon, but not by choice – an enormous sentient city on the planet drains so much energy from everything around it that the TARDIS is quickly rendered powerless. And the Doctor is not the only unwelcome visitor on Exxilon: an expedition of humans is there mining a substance necessary to cure a plague on Earth, though their ship is now useless. They called for backup from a relief ship, but to their horror, the ship that shows up comes down for a hard landing…and in any case, it’s not another human expedition. The ship that arrives is full of Daleks, on a mission seeking that same precious drug. As the human expedition’s weapons are useless, they and the Doctor are powerless as the Daleks line them up for extermination.
