Colter Shaw Goes Off The Map.
Tracker is back for Season 4, and tonight’s “Switchback” drags Colter out of the city and onto a rugged Pacific Divide Trail with a mother and daughter missing and someone on their tail.

Tonight: “Switchback”
Season 4, Episode 2. Spoiler-free setup below.
A Search That Turns Into A Hunt
A mother and daughter vanish while backpacking the Pacific Divide Trail, and what looks like a standard wilderness search-and-rescue is anything but. As Colter Shaw (Justin Hartley) starts tracking, he learns the pair had been stalked before they disappeared.
It’s a hard pivot from the premiere’s city setting: punishing terrain, a ticking clock, and the survivalist skill set that has defined Colter since the pilot. Cassady McClincy Zhang gets a prominent spotlight as the team’s newest member, Mel, working alongside Reenie.
