The Cybermen make their first ever appearance whilst William Hartnell's Doctor nears the end of his first incarnation, in this classic soundtrack adventure with linking narration by Anneke Wills.

The arrival of the Doctor, Ben, and Polly at the Base coincides with another landing, that of a spaceship whose humanoid passengers have used cybernetics to replace their limbs and vital organs.
