Some things happen on camera.
Some things only happen in the camera.
When forensic data analyst Gabriel Gleeson spots a shadow that isn't there in footage of a high-profile assassination attempt, he tells himself it's nothing. He has been wrong before. The establishment made sure everyone knew it.
But the shadow won't go away. And neither will the sixteen others he finds buried in six years of live broadcast records - the same fault, the same signature, different events, different continents, different camera systems. Someone, or something, has been inserting people into the digital record of reality. Not editing footage after the fact. Doing it in real time, frame by frame, across every screen on earth.
The question isn't who built it.
The question is how long it's been running.
As Gabriel traces the signal backwards - through dead scientists, classified facilities, and a treaty no government will admit exists - the world he thought he understood begins to come apart at the seams. Not dramatically. Not all at once. Just a frame here, a shadow there. Small errors in a system that is very nearly perfect.
It was never about the shooting.
The shooting was a test.
And humanity just passed.
