Justin Hartley‘s newest Tracker case finds Colter Shaw helping Paradise’s Jon Beavers look for his missing son.
In Us Weekly‘s exclusive clip from the Sunday, March 29, episode of the hit CBS series, Colter (Hartley) helps James (Beavers) up after he gets beat up. He then asks Sylvia what she knows about the boy’s disappearance.
“His son is missing, we are looking for him. He disappeared from the science center this morning,” Colter says. “This is his son, Alex. He is the same age as your older son. We are looking for the truth.”
James, meanwhile, jumps in to ask why Sylvia left “before the police had a chance to question” her. Sylvia denies taking the boy while defending how her past led to her losing custody of her own kids.

According to the official synopsis, Tracker‘s newest case is about how “when a young boy disappears during a school field trip at the aquarium, Colter must navigate a volatile father’s desperation to find his son.”
Beavers’ appearance on Tracker comes after his scene-stealing performance as Billy on Hulu’s Paradise. His is one of many high-profile cameos on Hartley’s show, which follows a survivalist who travels the country helping people and law enforcement tackle a variety of mysteries.
Hartley, 49, who is also an executive producer on the show, previously hinted at how far the show will push his character.
“I just love that when you watch a show like that and you tune into season 1 and then you tune into the last season, you see the development of the character and you go, ‘Wait a minute, are they playing different roles?’ But then if you watch it throughout the years, you experience those things with the characters,” he told TV Insider in September 2024. “As competent and confident as Colter is, I don’t at all think for a second that he doesn’t have a ton to learn, especially about himself and his family and all that.”

Hartley continued: “Going forward, I think that will be how the show lives on a long runway, is that we keep developing this character and he becomes better at what he’s doing. He’s a restless man, and for an audience member, at least shows that I love to watch, you love to see that growth of a character and we have that.”
The actor also warned that the character could die in the future.
“It’s important to keep upping the stakes. I like being Colter as a hero, finding people and all that. I also really like seeing him in a suspenseful thriller and a dangerous situation,” he told The Hollywood Reporter in April 2025. “I don’t want our audience to forget that this man is mortal, he’s not a superhero. He can die! The things he is doing are very very dangerous.”
Tracker airs on CBS Sundays at 9 p.m. ET.
