Overview
- Paramount+ announced the fourth and final season will premiere on November 20, 2026 exclusively for subscribers to its Premium plan on Thursday, August 20, 2026.
- Creators Ashley Lyle and Bart Nickerson will return as co-showrunners and executive producers for the concluding season.
- The streamer released a teaser and an official logline that center Season 4 on the survivors' race to hide their sins before rescue and the difficult homecoming that follows.
- Most principal cast members are confirmed to return, including Melanie Lynskey and Christina Ricci, and new recurring additions have been reported such as Molly Ringwald and June Squibb.
- Paramount says Season 3 was the series' most-watched season and its finale the most-watched episode; no episode count for Season 4 has been announced, and placing the finale on the Premium tier appears aimed at turning that audience momentum into subscriptions.
