Colter (Justin Hartley) is immediately thrown into a major case that kicks off Tracker season 2 this fall.

In the October 13 premiere, titled "Out of the Past," Colter makes a shocking discovery about the mother's past while investigating the strange disappearance of a missing family whose car is found abandoned on the side of the road in the woods of Arkansas, plunging him into the world of organized crime.

Looking ahead to what's in store for Colter early this season, beyond the family mystery surrounding his father's death, Hartley told TV Insider as part of our extended fall Season 2 preview: "What happens right away is we're introduced to a job that Colter got ten years ago. There's two sisters and one of them disappears. Colter gets hired, but he's never been able to crack it and it haunts him. For the first time, we see this guy who's such a hero and always does the right thing, but he couldn't find the girl and bring her back. It says a lot about him as a person that he carries that with him, but he doesn't let things go."

Also in the premiere, Reenie (Fiona Rene) opens her new law firm and enlists Velma's (Abby McEnany) help in building the case. You can see both Colter's work and Reenie's new office in the photos below.
