The robot Constantine notices an Artificial Intelligence spontaneously coming into being on a distant planet... and watches helplessly as it is destroyed. In deep space, far from Earth, Judy senses a change of mood aboard the passenger ship she travels on... and a quick investigation reveals that the craft is succumbing to a mysterious alien infestation.
Just as hope seems lost, a group of combat drones appears to rescue all the passengers, except Judy - who is told she is the property of a forgotten mega-corporation based on Earth. Returned against her wishes to an Earth under constant assault from the same alien infestation, Judy begins to learn her place in a conspiracy billions of years old.
But is she ready to take on the benign, omnipotent, all-seeing Watcher who guides human destiny? And destroy it?
