The Doctor and Clara, with theirold friend Rigsy, find themselves in a magical alien world, hidden on a street in the heart of London.
Sheltered within are some of the most fearsome creatures of the universe… and Ashildr (Maisie Williams)! With a death sentence hanging over their heads, not all of the intruders will get out alive.
NOTES
This is the first story to feature the Twelfth Doctor in a burgundy version of his signature navy blue Crombie coat, similar to the coat he was first seen wearing during The Day of the Doctor.
In the credited, the word “Oods” is used to denote more than one Ood, rather than the established “Ood”, as used in The Impossible Planet.
In one scene, there is a poster with a diagram of a flux capacitor, a direct reference to Back to the Future. It is accompanied by writings in Aurebesh, the main alphabet used in the Star Wars franchise. This writing spells out
“Delorean “, the car used in the Back to the Future franchise.
The Doctor previously has had to deal with dangerous countdowns. (42, Flesh and Stone)
Rigsy paints a mural on the TARDIS. This isn’t the first time it has been graffitied (Aliens of London) nor the first time someone has gone and painted it in his absence. (The Happiness Patrol)
