In an exciting return for fans, Justin Hartley reprises his role as survivalist Colter Shaw in the fourth season of CBS’s popular drama series ‘Tracker.’ The new season debuted on 4th October 2026, featuring an engaging storyline that sees Shaw diving into a complex case of a missing father linked to a sinister criminal network operating at the Port of Los Angeles.
Known for its gripping narratives, the latest season opens with an episode titled “Safe Harbor,” where Colter Shaw’s investigation begins when he is approached by a determined teenager who reaches out through a Reddit forum. Despite being recruited under dubious circumstances, Shaw feels a connection with the young boy and is compelled to assist in the search for his missing father. This scenario sets off a chain of events that uncovers startling revelations about larger issues hidden beneath the surface.
Hartley has revealed that the first plot of the season sets the stage for an even more significant narrative arc than viewers may anticipate. Speaking to TV Insider, he hinted that as the storyline develops, it becomes increasingly dark and intricate, culminating in a high-stakes situation that will test Colter’s skills and resilience. “When it starts to unravel, you begin to see just how expansive and stressful this case truly is,” Hartley expressed, alluding to the layered complexities that the new episodes will explore.
Filming for the fourth season transitioned from Vancouver to Los Angeles, a change Hartley welcomed enthusiastically. The actor, who also serves as an executive producer on the show, expressed pride in the earlier seasons but looked forward to introducing Colter’s stories in new settings. He articulated a desire to present fresh narratives that capture the essence of his character and the various challenges he faces on his journey.
As the season unfolds, viewers can expect Colter to confront uncomfortable truths about his own life, combined with the ongoing exploration of his complicated family history. The theme of hidden evils and secrets will become a recurring motif throughout the fourth instalment, adding depth to the overall narrative. Jensen Ackles returns in his role as Colter’s estranged brother, Russell, who holds a crucial secret revealed in the season three finale.
While CBS has not officially confirmed the total number of episodes for this season, previous seasons have seen a gradual increase in episode counts—from 13 in the first season to 22 in the third. With the show’s status as CBS’s top series, excitement surrounds the possibilities for ‘Tracker’ moving forward and its commitment to longer episode runs.
In explaining the series’ success, Hartley attributes its appeal to the unique twist on the procedural drama format. Working alongside executive producer Ken Olin, Hartley emphasised their shared vision to modernise the genre while allowing character development to unfold organically. “We wanted to breathe new life into an old genre,” he stated, noting that audiences seem to appreciate this fresh approach.
New episodes of ‘Tracker’ will continue to air weekly on Sundays at 9 p.m. ET on CBS, with the fourth season’s episode listings already including confirmed titles such as “Switchback” on 11th October and “Original Parts” on 18th October. Following the premiere, the series will revert to its regular airing time, providing audiences with a consistent viewing schedule.
For those looking to catch up with the series, all previous seasons of ‘Tracker’ are available for streaming on Paramount+. Subscribers can view new episodes as they air or access them on-demand the following day, giving fans a flexible way to enjoy the unfolding drama.
As ‘Tracker’ embarks on its fourth season, viewers can expect a thrilling blend of suspense, character exploration, and unforeseen twists that will keep them engaged week after week. With Hartley leading the charge as Colter Shaw, there’s much to anticipate from this dynamic show.
