The Patrick Troughton Years: 1966- 1969

Missing for nearly 25 years, full prints of "The Tomb of the Cybermen" were uncovered in Hong Kong in 1992. It remains the earliest complete Cyberman story.

The once feared Cybermen have disappeared from the universe without a trace. On Telos, homeworld of the extinct silver giants, a secret expedition arrives from Earth on a quest to find their last remains.

Having blasted through a mountainside to "a pair of doors," the archaeological party suffers their first causality just as the TARDIS materializes. As usual, the Doctor and his companions, Jamie and Victoria, have turned up at the worst moment, but the Doctor's ready knowledge of the Cybermen soon wins them a begrudging respect. Despite regular warnings from the Doctor, the expedition probes deeper and deeper into the site, whose Cyberman artifacts always seem to have a life of their own.
