Synopsis by Hal Erickson
In the first episode of a two-part story filmed in France, a Russian "K" agent, imbedded as a "sleeper", commits mass murder and then drops dead, aging rapidly as he expires. This occurs in 1965; twelve years agent, another long-imbedded "K" agent is likewise reactivated and likewise launches a murderous attack--this time on an empty house. Steed (Patrick MacNee) and his associates find out that there are 250 sleeper agents throughout France and England, all programmed to be activated by a Soviet satellite--which is now malfunctioning, unleashing death and destruction on an unsuspecting world. Former Avengers costar Diana Rigg appears as Emma Peel in scenes culled from the 1960s episodes "The Winged Avenger" and "The Hidden Tiger". Parts one and two of K is for Kill were telecast in the US as a "feature film" on March 23, 1979.
