Classic Who S7 • Serial 1 · (4 episodes)
Spearhead from Space
Forbidden to continue travelling the universe by his own people, the Time Lords, and exiled to Earth in the late 20th century, the newly regenerated Doctor arrives in Oxley Woods accompanied by a shower of mysterious meteorites. Investigating the occurrence is the United Nations Intelligence Taskforce (UNIT for short), an organisation which had previously been associated with the Doctor during the Cybermen's invasion.
Led as before by Brigadier Alistair Gordon Lethbridge-Stewart, UNIT is soon in action when people and meteorites start going missing. Most puzzling is the attempted kidnapping of a strange hospital patient: a man with two hearts, who insists that he knows the Brigadier.

As the newly-regenerated Doctor arrives on Earth, so does the Nestene too.
UNIT's attempts to locate the meteorites are hampered by the mysterious plastic Autons, being constructed by Channing at a nearby factory, while the Doctor makes another attempt to escape from the hospital.
Ransome manages to escape from the plastics factory and alert UNIT, prompting the Doctor and the Brigadier to start an investigation.
With UNIT's investigation being blocked by the Replica of Scobie, the Doctor and Liz visit Madame Tussaud's to try and find out more as Channing prepares to activate the Autons.
