The Tracker season 2 finale ended with the biggest revelation of the show so far, but that just set up a whole host of new questions for season 3 to answer. 'Echo Ridge' followed Colter Shaw (Justin Hartley) as a missing person's case in his hometown led him to uncover a child trafficking ring - and a surprise connection to his own father. One of his father's carvings, in the trailer of a trafficker, took him to a man who knew Ashton (Lee Tergesen), and Colter finally learned who was responsible for his death.
