It’s time to head back to the Lone Star state with 9-1-1: Lone Star. The 9-1-1 spinoff is now in its fourth season and the Ryan Murphy-Brad Falchuk creation shows no signs of slowing down. 

The team was put through their paces in season 3, from dealing with a catastrophic winter storm to trying to bring the station back together. We have no doubt that things will be even more intense in season 4. 

Here’s what we know about 9-1-1: Lone Star

9-1-1: Lone Star cast

Rob Lowe has come a long way since his role as Tony Flanagan in the 1979 series A New Kind of Family. Throughout the 80s, Lowe maintained his “Brat Pack” status by starring in films like The Outsiders and St. Elmo’s Fire. In the 90s, a slightly older Lowe was introduced to a new generation with his role as Benjamin Oliver in Wayne’s World. Of course, it was his memorable run on West Wing as Sam Seaborn that launched Lowe’s career into a whole new orbit. 

  • Rob Lowe (West Wing) as Owen Strand 
  • Gina Torres (Westworld) as Tommy Vega 
  • Ronen Rubinstein (Orange is the New Black) as T.K. Strand 
  • Sierra Aylina McClain (Empire) as Grace Ryder 
  • Brian Michael Smith (Queen Sugar) as Paul Strickland 
  • Rafael Silva (The Corps) as Carlos Reyes 
  • Jim Parrack (True Blood) as Judd Ryder 
  • Natacha Karam (The Brave) as Marjan Marwani 
  • Julian Works (Titans) as Mateo Chavez 

9-1-1: Lone Star plot

9-1-1: Lone Star follows in the footsteps of its sister show 9-1-1, only it’s set in Texas. Texas and LA have a few things in common but there’s no question that things are bigger in Texas. 

We don’t have a lot of information about what’s in store for season 4 just yet, but based on previous seasons we know that there’s usually a big event in the first few episodes that sets the tone for the new season. 

Last season the show kicked off with a story about a huge winter storm that threatened the lives of Texans everywhere. The story was incredibly true to life after a real storm left the region covered in dangerous ice and snow back in 2020.

We’ll add more about the season 4 plot as the details become available.
