special episode of Doctor Who

The main story arc of the series focused on the significance of the character of Clara, whom the Doctor had encountered twice before as Oswin in "Asylum of the Daleks" and as a governess in "The Snowmen". It also features the recurring appearance of the Doctor's enemy, The Great Intelligence.

The Doctor returns, alongside newly weds Amy and Rory, to face monsters and mysteries and adventures all across time and space. Together they find themselves in sixties America, battling the invasion the world forgot, then aboard a pirate ship on the high seas of 1696, to solve the mystery of the Siren. In a bubble universe at the edge of reality, the Doctor meets an old friend with a new face.

Prequel to series seven of Doctor Who (2005); five short films show the home life of Amy and Rory, while The Doctor has a few adventures of his own.
