'Why on Earth?' asked Nyssa disapprovingly. 'Why on Earth not?' replied the Doctor.
A group of palaeontologists have been savagely attacked while carrying out a study of fossilised dinosaur remains in an underground cave system on twenty-sixth-century Earth. A party of troopers and Professor Kyle, the only survivor of the attack, are investigating the deaths when they come across the Doctor and his companions at the site of the massacre. The time travellers are immediately suspected.
Adapted by the late Ian Marter — who also played the role of Harry Sullivan — from the original script by Eric Saward, Earthshock features the long awaited return of the Cybermen, the Doctor's most lethal enemies.
