The Cybermen take control of London as the population is enslaved and the Doctor and his friends become fugitives.
Lumic and the Cybermen are forcing the population to "upgrade" to cold, emotionless creatures like themselves. The Doctor, Rose, and Mickey join forces with the alternate-reality counterparts of Pete Tyler and Mickey Smith, in the search for the one weakness in the Cybermen's plans.—RTF
The Doctor and Rose, assisted by Peter Tyler, decide that the only way to stop the Cybermen is to infiltrate Lumic's factory and destroy it. The culling of the human population has started in earnest and Peter reveals that Lumic is ill and the Cybermen project started as a means of prolonging his life. The doctor thinks he has a way to overload the Cybermen - with emotion - but in order to do so, he will need access to Lumic's computer system. At the end of it all, Mickey comes to a momentous decision.—garykmcd
