Tracker Season 3 Episode 22: "The Best Ones" – Colter and Russell search for a victim of a nefarious research project. Jensen Ackles returns as Russell. Written by Elwood Reid & Travis Donnelly and directed by Ken Olin.

Justin Hartley is back as lone-wolf survivalist Colter Shaw in CBS's Tracker. Following last season's explosive finale, Colter is wrestling with hard truths about his family's history. In the wake of these shocking revelations, and aided by his trusted team, Colter must put the past in the rearview to focus on what he does best: using his instincts and survival skills to find the missing and collect rewards. Also starring Fiona Rene (Reenie Greene), CBS's Tracker is executive-produced by Hartley, Reid, Ken Olin, Connie Dolphin, Sharon Lee Watson, and Alex Katsnelson.
Kathleen Robertson (The Expanse, Swimming with Sharks) and Mark Engelhardt (American Horror Story, NCIS) have joined the cast in recurring roles. Robertson's Maxine is described as "a successful attorney at a major firm looking to engage Reenie (Fiona Rene) on what Maxine assures her is simply grunt work for an upcoming class action suit. It quickly becomes clear, however, that Maxine may have an entirely different game that she's playing." Meanwhile, Engelhardt's Emile Lang is described as "a man with his own moral code" who is "cold, calculating, and methodical."
