The episode starts with Clara explaining to a cyberman that Clara Oswald does not in fact exist and she is really another regeneration of the Doctor; and que the opening credits! The camera then cuts to the Doctor and the Mistress outside St Pauls with the cybermen, then Kate Walsh and her team hand cuff and capture Missy and then made them sleep. We then see Danny Pink in the after life watching the lights go out and his friend tells him that they are going back and they're going to be upgraded. After that we see the cybermen blow themselves up and turn into rain but it's only raining inside the grave yard. A funeral home is the next scene, the water seems to define gravity and travel up the walls to the bodies. But there is a body on the table, and when he turns into a cyber, the worker runs but the cyberman looks in the mirror almost confused as to what he has become and he grabs a piece of paper revealing that he is Danny Pinks cyberman. For the next part we're in a plane and it is revealed that the Doctor is the President of planet Earth. Clara begins listing information about the Doctor still trying to convince the cybermen that she's the Doctor when she says "ask anyone I know, I'm an incredible lier" and cyberman replies "correct" then kills the other three cybermen and shocks Clara, but if you look really closely you can see the paper in his hand.
