It's past the danger point. One of the machines nearest to the travellers suddenly speaks in a grating metallic voice.) Plead with them...anything! SUSAN: (To the DALEK.) TARDIS. Their only value is in bringing us enough of the Thal drug to duplicate it for our own use. They are squat and rounded with no discernable humanoid features. They pass through.) They're intact.

They convince the Thals of the need to fight for their own survival. Joining forces with them and braving Skaro's many dangers, they launch a two-pronged attack on the Dalek city. The Daleks are all killed when, during the course of the fighting, their power supply is cut off.
