Tracker Season 4 Moves to Los Angeles, Justin Hartley's CBS Hit Gets a New Look
CBS's top-rated drama Tracker is undergoing a major transformation. The Justin Hartley-led series, which remains the number one scripted show on network television, is relocating production from Vancouver to Los Angeles for its fourth season. The move brings a fresh visual identity to the show while keeping its core premise intact.
Tracker Season 4 premieres Sunday, October 4, with Hartley returning as Colter Shaw, the self-described rewardist who crisscrosses the country finding missing people. The series has consistently drawn roughly 17 million multiplatform viewers per episode, cementing its status as a network powerhouse since its debut in 2024.
Why is Tracker moving production to Los Angeles?
The production shift is historic. Tracker received the largest tax incentive ever awarded by the California Film Commission to relocate its filming operations. The first three seasons were shot in Vancouver and throughout British Columbia, where dense forests and rugged terrain served as the backdrop for Colter's cases.
Now, California's landscapes take center stage. The official Season 4 promo shows Colter working a case at the Port of Los Angeles, searching for a missing father. Additional scenes feature rural locations and natural scenery across the state, effectively turning California into a new character for the series.
What else is changing in Tracker Season 4?
The location shift is just one of several changes reshaping the show. Throughout Season 3, Tracker expanded its storytelling beyond the case-of-the-week format that defined its early episodes.
Reenie Green, played by Fiona Rene, has stepped into a more prominent role. Her character now carries independent storylines centered on her criminal law firm, including a class-action lawsuit she pursues with Melanie Day, portrayed by Cassady McClincy Zhang.
The series has also leaned into more speculative territory. Colter and his brother Russell investigated the Chrono Stasis Institute, their father's former employer, uncovering young adults whose abilities are being weaponized for military applications. These plotlines touch on remote viewing and astral projection, pushing the show into genre territory fans didn't see in Season 1.
Will Tracker keep its loyal audience?
Despite the changes, the show's anchor remains unchanged: Hartley's Colter Shaw. His go-anywhere mentality allows the series to adapt to new settings without losing its identity. As long as that core remains intact, Tracker appears positioned for a long run.
The show is based on the Colter Shaw book series by Jeffery Deaver and was created by Ben H. Winters. Elwood Reid serves as showrunner.
When does Tracker Season 4 premiere?
Tracker Season 4 debuts Sunday, October 4 on CBS. The series airs in its usual time slot and will be available for streaming on Paramount+.
For Iowa viewers who have followed Colter Shaw since the beginning, this season promises a visual refresh while delivering the same high-stakes rescue missions that made the show a hit.
