Production for Tracker Season 4 has officially moved to Los Angeles, and new images from the set confirm that Colter Shaw will once again cross paths with his brother, Russell. The upcoming season is scheduled to premiere on CBS on October 4, 2026, at 9:30 p.m. ET, marking a significant shift in both the show’s setting and the central family dynamic.
The reunion between Justin Hartley’s Colter and Jensen Ackles’ Russell carries significant narrative weight following the events of the Season 3 finale. While the brothers appeared to be mending their fractured relationship, Russell was seen withholding a critical piece of information: a secret file regarding their father’s past DARPA experiments. Reports indicate that Russell followed the orders of the series’ antagonist, McIntyre, to keep the file hidden, essentially betraying Colter’s trust to protect a mystery that could rewrite their family history.

A New Backdrop in Los Angeles
The fourth season represents a major logistical change for the production, which has permanently relocated from Vancouver, British Columbia, to Southern California. This move was facilitated by a record-breaking $48 million tax credit from the state of California. For the first time, the series will be filmed in the country where its story is set, shifting the show’s visual identity from the dense forests of the Pacific Northwest to a more urban and coastal environment.
This geographic shift is immediately reflected in the Season 4 premiere. Titled “Safe Harbor,” the first episode reportedly centers on a case involving a criminal operation at the Port of Los Angeles. The move to a major metropolitan hub is expected to influence the “case-of-the-week” format, trading rural wilderness searches for high-stakes investigations within the city’s complex infrastructure.
Broadcast Schedule and Returns
Following its special 9:30 p.m. premiere on October 4, Tracker will move to its regular 9:00 p.m. time slot starting October 11. While the primary cast is set to return, the presence of Russell Shaw remains a focal point for fans. The “intense” reunion captured in recent set photos suggests that the fallout from the DARPA file secret will be addressed early in the season, even as the brothers are forced to collaborate on new cases.
The tension between the siblings serves as a secondary through-line for the series, which has balanced Colter’s professional work as a “reward seeker” with the ongoing mystery of his father’s death. With the production now based in Los Angeles, the show’s creators have more direct access to urban landmarks and coastal scenery, providing a fresh backdrop for the resolution of the Shaw family’s long-standing secrets.
