The Power of Three

Written by Chris Chibnall

"I'm not running away from things, I am running to them. Before they flare and fade forever. And it's alright. Our lives won't run the same. They can't. One day, soon, maybe, you'll stop. I've known for a while."

The Doctor and the Ponds puzzle an unlikely invasion of Earth, as millions of sinister black cubes arrive overnight, almost like presents falling from the sky. But what are they, what's inside them and most importantly, who sent them? With the international community at a loss, it's left to the Doctor to unearth who is behind the mystery.
