“Chrono Stasis,” Tracker Season 3 Episode 21, premieres Sunday, May 17 on CBS from 9:00 p.m. to 10:00 p.m. ET/PT. The episode reunites Sofia Pernas as Billie and brings Jensen Ackles back as Russell Shaw, with additional cast including Jerry Trimble and Jeri R
Tracker fans are getting another high-stakes reunion this week: Sofia Pernas is back as Billie after last week’s “Reclamation,” and this Sunday brings Jensen Ackles back into the story as Colter’s (Justin Hartley) brother Russell Shaw.
Episode 21, titled “Chrono Stasis,” centers on a family push that’s long overdue.. The official synopsis says: “Colter and Russell unite in a personal mission to uncover their father’s mysterious work.” It’s a pitch that’s both straightforward and tantalizingly broad—the kind of setup viewers have been waiting for.
“Chrono Stasis,” written by Sharon Lee Watson & Amanda Mortlock and directed by Jeff T. Thomas, also includes Jerry Trimble and Jeri Ryan, based on first-look photos.
If you’re asking what time to tune in on Sunday, May 17: Episode 21 premieres on CBS from 9:00 p.m. to 10:00 p.m. ET/PT, right after a new episode of Marshals.
The season’s endgame is already lining up behind that schedule. Tracker Season 3 is set to run 22 episodes, and “Chrono Stasis” is labeled as the penultimate episode—meaning Episode 22, the Season 3 finale, airs next Sunday, May 24.
There’s also a wider-picture promise for fans planning ahead. Tracker received an early Season 4 renewal back in January. An official Season 4 release day hasn’t been announced yet, but if the show follows past schedules, new episodes are expected in the fall.
Streaming options are part of the planning too. Tracker episodes are available on Paramount+. Paramount+ has two subscription plans: Essential, which costs $8.99/month and is ad-supported, and Premium, which costs $13.99/month, is ad-free, and includes Showtime titles and live CBS.
For Hulu, the situation is different.. New episodes of Tracker Season 3 aren’t available there the day after they air on CBS.. But Tracker Season 1 and Season 2 are streaming on Hulu, and all 33 episodes are available.. Hulu’s 30-day free trial applies to its basic, with-ads plan.. After the trial, it costs $10.99/month, while ad-free Hulu costs $18.99/month.
If you’re looking to bundle services, Disney+ bundles that include Hulu are also listed as an option. Those bundles start at $12.99/month for ad-supported Disney+ and Hulu, and they go up to $32.99/month for Disney+, Hulu, and Max, all ad-free.
The pattern is built into the broadcast calendar: Episode 21 airs Sunday, May 17 on CBS from 9:00 p.m. to 10:00 p.m. ET/PT, and the next Sunday, May 24, is when Episode 22—the Season 3 finale—takes over, making “Chrono Stasis” the penultimate stop on a 22-episode run.
