Mondas, ancient fabled twin planet of Earth has returned. Soon its inhabitants arrive. But while they used to be just like the humans of Earth, now they are very different. Devoid of emotions, their bodies replaced with plastic and steel, the Cybermen are here.
Humanity needs all the help it can get, but the one man who seems to know what's going on is terminally ill. As the Cybermen take over, the Doctor is dying...
