Synopsis by Hal Erickson
In the conclusion of the four-part story "Spearhead From Space," the final pod has been found and the Nestene Consciousness is able to reconstruct itself on Earth. This will mean disaster for everyone on the planet unless the Doctor (Jon Pertwee) finds some way of disabling the Consciousness' warriors, the Autons. More than one commentator has noticed the remarkable resemblance between this Doctor Who continuity and Nigel Kneale's sci-fi classic Quatermass II. First telecast January 24, 1970, "Spearhead From Space, Episode 4" was written by Robert Holmes.
