tvtv.de has an intersting synopsis of the episode, thought it doesnīt really tell us anything new, I translated it for you:
Some information for german Who fans on the board:
It seems most Cinemaxx cinemas are showing The Day of the Doctor, note since itīs delcared as an event by Cinemax, ticket reservation is only possible for silver or gold card holders. Everyone else has to have luck to get any tickets.
FOX (via Sky or Kabel Deutschland Digital) is showing it at 21:00, note that it seems its dubbed there since its beeing advertised with a german title.
