On the planet Telos, the Doctor and his friends encounter a party of archaeologists intent on uncovering the mythical "tomb of the Cybermen". Only the Doctor seems aware of the folly of this venture, but suddenly it's too late, the ice tombs are open, and the Cybermen are coming back to life.
Patrick Troughton plays the second Doctor in this four-episode adventure from 1967, set on Earth's moon and featuring a return appearance by the emotionless Cybermen. The year is 2070, and the Earth's weather is controlled by a device called the Gravitron which is under threat from a plague epidemic and the Cybermen.
