This is a piece of fan fiction that was posted on YouTube on 3rd Oct 2015 by dalek1099 and consists of old clips of Doctor Who assembled in such a way as to tell a new story. To be honest I don't know why this appears on IMDb because listing it here implies it is genuinely part of the BBC's Doctor Who series which it certainly isn't.
