Justin Hartley's hit series Tracker is taking the cast changes in stride in season 3 following multiple exits. CBS released the first look at the new season on Wednesday, September 24, which spoiled Us with scenes of Colter (Hartley) body-slamming someone, channeling his inner cowboy while riding a horse and solving cases left and right. "If you want me to help you, you got to tell me everything," Colter said in the sneak peek. "In my experience, every second counts." Fans also got to see Jensen Ackles return as Colter's brother, Russell.
