In the third episode of the six-part story "Genesis of the Daleks," the Doctor (Tom Baker) has been sent back in time to the planet Skaro, under orders to prevent the creation of the mutant Daleks. Complicating matters is the fact that the Doctor and his friends find themselves in the middle of the never-ending conflict between the Kaleds and the Thals, whose nuclear war has thrust Skaro into a second Stone Age. One of those Kaleds is the demented, deformed genius Davros (Michael Wisher), who holds the key to the Daleks' creation. First telecast on March 22, 1975, "Genesis of the Daleks, Episode 3" was written by Terry Nation. ~ Hal Erickson, Rovi
