Synopsis by Hal Erickson
Recovering from a broken leg at a private convalescent home, Steed soon learns that he is being stalked by a mysterious assailant. The would-be killer turns out to be an old enemy, who intends to kill Steed exactly seven years after he himself was thrown in jail. Physically unable to repel his enemy, Steed must rely upon Tara for salvation. Blatantly inspired by the American movie classic High Noon, "Noon Doomsday" was written by Terry Nation; it was first shown in America on October 28, 1968, and in England on November 27 of that same year.
