The roughly 30-second teaser wastes little time putting Colter (Justin Hartley) back to work, showing him sliding beneath a moving truck, dodging boulders, fighting, driving, and searching through rugged terrain. Colter describes his work simply as “finding people,” before Randy (Chris Lee) calls about a missing single father “who left home last night and never came back.”
Another mother begs him to “please find my daughter,” and Colter replies, “I’ll do everything I can.” Between the desperate calls and fast-paced action, the teaser shows Colter returning to the dangerous work he knows best, with new cases already waiting for him in Tracker Season 4.
