CBS's missing-persons drama Tracker will return for its fourth season on 4 October, with episodes streaming on Paramount+ from the following day. The show, starring Justin Hartley as drifter Colter Shaw, has proven notably prolific for a modern network series, producing three full seasons in under two years since its debut at the end of 2024.

For the first time, Season 4 was filmed in Los Angeles rather than Vancouver, where the previous three seasons were shot, and CBS has released the first official image alongside a synopsis for the premiere. Hartley returns alongside co-star Jensen Ackles, and the opening episode will see Colter searching for a teenage boy's missing father, a case that draws him into a dangerous criminal operation at the Port of Los Angeles.
