In the second episode of the four-part story "Frontios," the Doctor (Peter Davison) and his companions have made contact with a group of survivors from a nuclear holocaust on planet earth who have pitched camp on the futuristic planet Frontios. When the colonists begin disappearing in a mysterious but dramatic fashion, the Doctor investigates, all the while steeling himself against the incessant bombardment of meteors which has been plaguing Frontios since his arrival. Originally telecast on January 27, 1984, "Frontios, Episode 2" was written by Christopher H. Bidmead. ~ Hal Erickson, Rovi
