What links a diamond raid in 20th Century London, a secret base in the heart of the city's sewer system, a cold and desolate planet light years from Earth, and a daring plan to alter the entire course of interplanetary history? The Doctor's old enemy, Lytton, has allied himself with the Cybermen. Their scheme, if successful, could bring the human race to its knees. For the Cybermen have journeyed back in time to prevent the destruction of their home world. And for Mondas to survive, the Earth must die...

The Doctor and Peri land on the planet Necros to visit the funerary home Tranquil Repose - where the dead are interred and the near-dead placed in suspended animation until such time as their conditions can be cured. But the Great Healer of Tranquil Repose is far from benign. Under his command, Daleks guard the catacombs where sickening experiments are conducted on human bodies. The new life he offers the dying comes at a terrible cost - and the Doctor and Peri are being lured into a trap that will change them forever.
