Synopsis: A UFO lands in England, and hypnotically controls 3 people nearby - Linda Simmons, Daniel Clark, and Carl Mason. Miss Simmons then strangles a policeman with superhuman strength given to her by the UFO. Clark then attacks Commander Straker in his car, and gives him a written ultimatum that a SHADO tracking station, Skydiver 3, and SHADO HQ will be destroyed if they do not cease operations immediately. Sure enough, Clark breaks into the tracking station, and when he grabs some high voltage power cables, the station explodes. Mason then similarly destroys Skydiver 3 after getting past security. Due to the report of the strangled policeman near Clark and Mason's homes, Foster is sent to investigate Miss Simmons. He then brings her to SHADO HQ -- the next target for destruction! [Spoiler]
Writer: Tony Barwick.
Featured Characters: Straker, Foster, Lake, Jackson
Review: A very good episode, with a fairly good guest cast, stylishly done, and some great explosion sequences. Grade: B+
Note: This is one of two episodes (the other is CONFETTI CHECK A-OK) that does not begin with the standard opening sequence. The Japanese UFO laserdiscs add an opening sequence to the episode, but this is technically not correct.
