The First Doctor (William Hartnell), Ben, and Polly find themselves in Antarctica in 1986, during the approach of Earth’s former twin planet Mondas. The inhabitants of Mondas, the Cybermen, have a plan in store for humanity: converting them to Cybermen and absorbing all the energy of the Earth! This, of course, is a dumb plan. But General Cutler feels like bombing everybody anyway.
Steve and Andrew ponder this story, while also finding themselves stranded in both space and Antarctica. Then the guys get an up-close exclusive interview with Cyber leader Regos Krang, although Krang and Andrew don’t see eye to eye.
