The first responders of the 118 are facing their most extreme emergency yet—one that stretches from the streets of Los Angeles all the way to outer space. A new trailer for the upcoming season reveals that Athena Grant-Nash and Henrietta “Hen” Wilson will be part of a dangerous space mission, while a geomagnetic storm threatens chaos back on Earth. The new season will also see the tight-knit team navigating the profound loss of their captain, Bobby Nash.
The ninth season of the hit procedural drama is set to premiere on Thursday, October 9, 2025, at 8/7c on ABC. The season will consist of 18 episodes. New episodes will be available for streaming on Hulu the day after they air on television.
What is the plot of 9-1-1 Season 9?
The official trailer for Season 9 sets up a high-stakes storyline. The 118 rescues a billionaire named Trip Hauser, played by Mark Consuelos, after he is swallowed by a whale. In gratitude, Trip invites Hen to join him on a historic space flight. Hen first asks her wife, Karen, but Karen declines, stating, “I am a serious scientist. Trip Hauser doesn’t care about serious science. I can’t go to space.” Hen then turns to her friend Athena, who initially responds, “Are you crazy? Absolutely not,” but eventually agrees to go.
The journey takes a dangerous turn when Trip knowingly launches the spacecraft despite warnings about a geomagnetic storm. The storm causes the team to lose all contact with the vessel, leaving Athena and Hen in a perilous situation in space while the 118 deals with the resulting chaos in Los Angeles. The trailer ends with a cliffhanger showing Hen grabbing onto Athena as she floats outside the spacecraft.
This season also deals with the aftermath of Captain Bobby Nash’s death in Season 8. The team is left to grapple with his absence, which is expected to shift partnerships and roles within the firehouse. Showrunner Tim Minear has described Season 9 as “The Season of Perpetual Grappling,” noting that “when one piece as pivotal as Bobby is taken away, everything shifts.”
Who is in the cast of 9-1-1 Season 9?
With the exception of Peter Krause, who played the late Bobby Nash, the main cast is returning for the new season.
The returning series regulars include:
- Angela Bassett as LAPD Sergeant Athena Grant-Nash
- Oliver Stark as firefighter Evan “Buck” Buckley
- Aisha Hinds as firefighter and paramedic Henrietta “Hen” Wilson
- Kenneth Choi as firefighter and paramedic Howard “Chimney” Han
- Jennifer Love Hewitt as dispatcher Maddie Han
- Ryan Guzman as firefighter and paramedic Edmundo “Eddie” Díaz
Additionally, two actors have been promoted to series regulars for Season 9:
- Corinne Massiah as May Grant, Athena’s daughter
- Elijah M. Cooper as Harry Grant, Athena’s son
Mark Consuelos will appear in a guest-starring role as the billionaire Trip Hauser, and June Diane Raphael will play a character named Tricia Benoit, who also goes to space.
Who is the new captain of the 118?
Following Bobby’s death, the firehouse needs a new leader. The Season 8 finale set the stage for Chimney to step in as the interim captain. After delivering an impassioned speech that stopped Buck from transferring and Eddie from moving to Texas, Chimney solidified his role. Both Aisha Hinds (Hen) and Oliver Stark (Buck) have expressed their support for this decision in past interviews, with Stark noting that Buck looks up to both Hen and Chimney as natural successors to Bobby.
Where can I watch 9-1-1 Season 9?
9-1-1 Season 9 will air on ABC on Thursday nights. The premiere on October 9 will be followed by the debut of the new spinoff, 9-1-1: Nashville, and the Season 22 premiere of Grey’s Anatomy. For those who stream their shows, full episodes will be available on Hulu the day after their broadcast premiere.
What are the upcoming episode details?
A few episode titles for the new season have been revealed through the WGA website. The first episode is titled “Eat the Rich,” and its synopsis reads: “In honor of Bobby Nash’s sacrifice, the 118 comes together to dedicate the firehouse in his memory. Meanwhile, when a billionaire tech giant is involved in a life-or-death emergency, the team must race to his aid.” This episode will feature the rescue of Mark Consuelos’ character from the whale. Other confirmed episode titles include “Spiraling,” “The Sky Is Falling,” “Reentry,” and “Day of the Dead.”
Showrunner Tim Minear has hinted that by the end of the third episode, “The Sky Is Falling,” Athena will have a new connection to the 118. This has led to speculation that her son, Harry, may decide to join the firehouse, a decision that would likely create tension with his mother.
