A former investigator is pulled back into a buried case when a series of murders unfold with eerie precision, each victim warned in advance and found exactly as predicted. As Elias Vance follows the pattern, he uncovers a hidden system designed to study and control human behavior, one that has been operating in secret for years. With his own movements now part of the experiment, Elias must outthink an unseen architect before he becomes the final proof of their design.
