神秘博士：博士之时

The Doctor arrives in Victorian London. It's Christmas, but snow isn't the only thing descending on the tranquil and jubilant civilization, as familiar silver giants from an alternate reality are amassing in numbers. The Cybermen are on the move again, and the only beings who can stop them are the Doctor and... another Doctor?

The Doctor has retired to 1892 London. Despite the protests of his allies, he is determined to keep out of mankind's affairs. However, a governess named Clara has stumbled upon a plot which only the Doctor can unravel, involving the death of her predecessor in ice and the sinister Dr. Simeon, who controls monsters made of sentient snow. And there is another mystery afoot: Clara is the spitting image of Oswin Oswald, whom the Doctor saw die in the Dalek asylum...

It's Christmas Eve, 1938, when Madge Arwell comes to the aid of an injured Spaceman Angel as she cycles home. He promises to repay her kindness - all she has to do is make a wish.

As the Twelfth Doctor nears regeneration, he stumbles on his first incarnation, also refusing to change. It takes a captain, a glass avatar and a familiar face to convince the Doctors the universe still needs them.

Before the Doctor can settle down to married life, he must face one last confrontation with his deadly enemy of certain death - the Master.

In 2013, something terrible is awakening in London's National Gallery; in 1562, a murderous plot is afoot in Elizabethan England; and somewhere in space an ancient battle reaches its devastating conclusion. All of reality is at stake as the Doctor's own dangerous past comes back to haunt him.

The newly-regenerated Doctor arrives in Victorian London, and Clara Oswald struggles to embrace the man he has become. All the while, they reunite with the Paternoster Gang to investigate a series of combustions that have been occurring all around the city.

The Doctor and Clara face their Last Christmas. Trapped on an Arctic base, under attack from terrifying creatures, who are you going to call? Santa Claus!
