The TARDIS arrives on Earth in the 26th Century in a cave system containing numerous dinosaur fossils. The Doctor’s party comes under suspicion from a military force, led by Lieutenant Scott, who are investigating the disappearance of a group of palaeontologists and geologists. They are all then attacked by androids – the true culprits – under the control of the Cybermen. The Doctor manages to deactivate a bomb intended by the Cybermen to destroy an imminent peace conference. He then follows the bomb’s activating signal to an approaching space freighter, commanded by Captain Briggs, on board which it transpires that an army of Cybermen are concealed.
