The Doctor and companions find themselves on a parallel earth this week. Aside from the Zeppelins, Rose's dad still alive, and the Cybermen, it's pretty much the same earth we all know. Ok, so there are a fair amount of different things on this earth.
But the big thing this week is the return of a fan favorite, the Cybermen. They're on the same mission as they always are, but in this adventure they're dressed in the hottest fall fashion exoskeletons.
