Justin Hartley returns in Tracker Season 4 with cast changes

The fourth season of the CBS series Tracker debuts this Sunday, October 4, featuring Justin Hartley in his role as Colter Shaw. Viewers should note a specific timing adjustment for the opening episode compared to standard scheduling.

Premiere Air Time Details

The broadcast begins at 9:30 p.m. Eastern Time on the CBS network. For audiences on the West Coast, the airing is set for 9 p.m. Pacific Time. This represents a half-hour delay from the show’s typical East Coast slot.

The shift occurs because the entire Sunday evening lineup moves back by thirty minutes, with Marshals starting at 8:30 p.m. ET. This later start applies only to the premiere night. CBS has not provided an official explanation for the change, though ScreenRant indicated it may stem from earlier NFL coverage on the network.

Starting next week, on Sunday, October 11, Tracker will revert to its regular 9 p.m. ET/PT timeslot.

Episode Plot and Viewing Options

Titled “Safe Harbor,” the premiere follows Colter Shaw as he investigates the disappearance of a teenage boy’s father. The narrative places him within a hazardous criminal operation located at the Port of Los Angeles, according to Paramount.

Audiences can tune in live via CBS. The program is also accessible through Paramount+. Premium plan subscribers receive live streaming access during the broadcast, while Essential plan members can view the episode on demand the following day. New episodes are scheduled to air weekly on Sunday nights.

Season 4 introduces modifications to the cast lineup. Reports have detailed which actors are confirmed to return, those who will not appear, and other significant personnel changes.
