Trackeris back this Sunday, and when the show returns, a case that has bugged Colter (Justin Hartley) for over a decade takes center stage. Despite failing initially to find Gina Pickett, Colter has never moved on from her disappearance all these years later. Colter now has a companion, and in Tracker Season 2, Episode 9, "The Disciple," the duo makes great headway in figuring out what happened to Gina. The logline below for the February 16 episode previews Keaton's (Brent Sexton) return and developments in the case. CBS released a sneak peek of the midseason premiere, showing Colter revisiting the case with fresher and more experienced eyes.
