The TARDIS arrives on the planet Telos where an Earth archaeological expedition led by Professor Parry is attempting to uncover the lost tombs of the Cybermen. With a lot of help from the Doctor the archaeologists succeed in entering the tombs.
Once inside, the party’s financier, Klieg, reveals that he and business partner Kaftan are planning to revive the Cybermen. He and Kaftan are members of the elitist Brotherhood of Logicians and they want to use the Cybermen’s strength to create an invincible force for the conquest of Earth.
However, the tomb is actually a giant trap designed by the Cybermen to lure humans suitable for conversion inside and augment their own forces. It’s a fate that almost befalls Kaftan's assistant Toberman but is halted before he is fully converted.
After fending off an attack by small but dangerous cybernetic creatures called Cybermats, the Doctor defeats the revived Cybermen and reseals the tombs. The Cybermen leader, the Controller, is apparently destroyed in the process.
Thought lost for decades, The Tomb of the Cybermen acquired a reputation for being one of the all-time great classic stories. When it was found in 1991 and finally seen again, the general opinion was that it was perhaps overrated. While it does have several rather large flaws, overall the story remains the finest Cyberman story of the Troughton era, and contains more than enough essential moments to warrant its status as a "classic."
