The story is in process, but here is the synopsis of my idea for the 4/Weeping Angels story.
“Concrete and Steel”
The Doctor just finished calibrating his new K9 - Mark II, and decides to test him. And the opportunity presents itself - the TARDIS picks up a distress signal. However, it is seriously corrupted, so K9 must decipher it, while the Doctor heads off to investigate (against K9’s advice).
As the Doctor proceeds into the facility from where the signal was sent, he stumbles upon the sender, who seems extremely familiar…
K9 heads to the rescue, only to find that the facility is filled with lifeforms that move only when he looks at them… A lifeform that the Doctor… or rather, Doctors… hoped to never encounter ever again… The Weeping Angel.
