Though Tracker offers a unique approach to the procedural format, Tracker season 3 should make one big change to the way Colter Shaw’s team operates to make the series even better. Tracker is inspired by The Never Game by Jeffrey Deaver, which kicks off a series of novels about the character. The TV show follows Colter Shaw (Justin Hartley) as he travels around the United States, finding people who are missing in exchange for the rewards offered.
