First broadcast in four weekly parts from 28 May to 18 June 1966. In this early story, the Doctor (William Hartnell) and his travelling companions Steven (Peter Purves) and Dodo (Jackie Lane), arrive on an unnamed planet where they encounter two distinct people - the Elders and the Savages. They soon discover the Elders are the evil ones, draining the primitive Savages for their life source to remain young and powerful forever. This story marks the final appearance of Purves as Steven. This will be a three-disc release including all four animated episodes in colour and black and white, plus brand-new bonus features.
