Tracker Season 4 is now airing on CBS, with Justin Hartley back as reward seeker Colter Shaw. The season opened on Sunday, October 4, 2026, and has already moved through its first three episodes. A new case arrives every Sunday, and the show has settled back into its familiar 9 p.m. ET/PT slot after a one-week delay for the premiere. For viewers who want to plan their Sundays or catch up later on streaming, here is the full confirmed schedule, episode details, cast information, and global streaming guide.
Premiere Date and Regular CBS Time Slot
Tracker Season 4 premiered on Sunday, October 4, 2026, at a special time of 9:30 p.m. ET/9 p.m. PT on CBS. The delayed start followed the season two premiere of Marshals. From Sunday, October 11 onward, the series returned to its usual 9 p.m. ET/PT slot.
CBS renewed Tracker for a fourth season in January 2026, while Season 3 was still airing. The network confirmed the fall premiere date later in the year, keeping the show on Sunday nights where it has been one of the most-watched broadcast dramas in the United States.

What Happens in Each Confirmed Episode
Each episode follows Colter Shaw as he takes on a new missing-person case while the larger Shaw family story continues in the background. The confirmed synopses give a clear picture of where the season is heading.
“Safe Harbor” sends Colter to the Port of Los Angeles to search for a teenage boy’s missing father. The case pulls him into a dangerous criminal operation.
“Switchback” follows a mother and daughter who vanish while hiking the Pacific Divide Trail. Colter races to find them after learning they were being stalked.
“Original Parts” takes Colter to a deserted Texas town to track down a woman who disappeared after an argument with her husband. The episode also brings an unexpected reunion for Reenie Greene with an old friend, Adam Shevlin, played by Michael Malarkey.
“Purification” centers on a woman who disappears after helping a terrified teenage runaway. Colter uncovers a disturbing case of abuse and works to save both of them.
“Need to Know” brings Jensen Ackles back as Russell Shaw. A military contractor’s wife and daughter are kidnapped, and Colter learns that Russell is investigating a related lead. The Shaw brothers join forces to uncover a high-stakes cover-up.
How Many Episodes Will Season 4 Have
CBS ordered 22 episodes for Tracker Season 4, matching the show’s previous full-season pattern. The exact number of episodes that will actually air has not been officially confirmed by the network, but the 22-episode order gives the season enough room to run through the 2026-2027 broadcast year.
Season 1 had 13 episodes, Season 2 had 20, and Season 3 had 22. Tracker Season 4 is on track to match or come close to the Season 3 count.
