Doctor Who Spearhead from space (1)

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. The new Doctor soon joins forces with his old friend, with UNIT, and with the recently recruited Dr Elizabeth Shaw, but time is running out. Irregular things are happening at a nearby plastics factory, while faceless creatures lurk in the woods. The Nestenes have landed a spearhead force and plan to conquer the country by substituting plastic Auton replicas for men and women in key government and military posts.
