The Doctor meets Professor Parry and his archaeologists on the planet Telos. The expedition is there to unearth the remains of Cybermen who died out five centuries before. Or did they?
Professor Parry and his team begin to unlock the secrets of the Cybermen’s tomb. But there are some amongst the explorers who have a dark agenda of their own.
The tombs are revealed to be a trap. The Cybermen have risen from their centuries long hibernation and are intent on converting the humans into a new race of Cybermen.
The Cyber Controller has been revitalised after leaving the icy tomb, threatening to overpower his human foes. The Doctor is determined to return the Cybermen to their long sleep.
