In the third episode of the six-part story "The Invasion of Time," the Doctor (
Tom Baker) continues to assist the telepathic Vardans, even though they intend to conquer his home world of Gallifrey. Actually, the Doctor has a different agenda in mind -- but, lest the Vardans tumble to his scheme, he is forced into some truly bizarre behavior, including the banishment of his loyal traveling companion, Leela (Louise Jameson). First telecast February 18, 1978, "The Invasion of Time, Episode 3" was written by Graham Williams and Anthony Read, under the joint pen name of David Agnew. ~ Hal Erickson, All Movie Guide
