"9-1-1, what's your emergency?"

9-1-1: Lone Star is a firefighter and rescue procedural drama created and produced by the creative trio of Ryan Murphy, Brad Falchuk, and Tim Minear (known collectively for their work on American Horror Story), which was ordered by Fox in May 2019, it premiered January 19, 2020.

It is a spinoff of 9-1-1.

Taking place in Austin, Texas, the series tackles the lives of the 126 Fire House. After the fire house's rebuilding, a sophisticated New York firefighter, Owen Strand (Rob Lowe), relocates from Manhattan to Austin along with his son, Tyler Kennedy "TK" (Ronen Rubinstein). Owen must try to balance the duties of saving those who are at their most vulnerable and solving the problems in his own life.

Other than Owen and TK, the 126 includes Judson "Judd" Ryder (Jim Parrack), Marjan Marwani (Natacha Karam), Paul Strickland (Brian Michael Smith), and Mateo Chavez (Julian Works). Judd is married to Grace (Sierra McClain), who serves as a 9-1-1 call operator. The 126 works in conjunction with paramedics from the Emergency Medical Services, including captain Michelle Blake (Liv Tyler) and Nancy Gillian (Brianna Baker), and officers from the Austin Police Department, including Carlos Reyes (Rafael Silva), who becomes TK's boyfriend. In the second season, Michelle resigns as captain of the EMS and is replaced by Tommy Vega (Gina Torres).

A recap page is in the works. Contributions are appreciated.

This show provides examples of:

  • AB Negative: In "Friends Like These" (1.06), the driver of the car crash needs a blood transfusion, but the hospital can't get to the accident site until at least an hour, her passenger, who came out of the crash unsacthed, tells Michelle that she is O-, the universal donor, and can be used for a field transfusion.
  • Action Prologue: The "Pilot" (1.01) opens with the original 126 Fire House trying to put out a fire at a fertilizer plant only for it to blow up and kill everyone on the team, bar one.
  • Actor Allusion: During a date, Owen describes how he imagines politicians' work in a way that sounds suspiciously similar to his work in The West Wing:
    Owen: I always imagine the world of politics to be really smart people waking briskly down corridors, talking real fast and all sort of sounding alike.
  • Artistic License – Medicine: Like the show it spun off from, this series can be quite...liberal with inaccuracies when it comes to actual medical treatment, among other things. During the first season, the real-life medical director for Austin-Travis County EMS took to social media warning their paramedics to not do anything they see on the show.
    • One of the most egregious examples easily comes from “Hold the Line” (2.03) where, after Judd gives JJ (a minor who is in shock) a speech to keep fighting to stay conscious, he punches him upside the head for good measure. Needless to say, not only would that not even remotely help the situation in real life, but it would almost certainly get him fired if not arrested.
    • Invoked in "Tommy Dearest" (4.07). During an interrupted date night with Trevor, Tommy diagnosed his daughter Melody with juvenile gastrocentesis. For context, Melody was faking nausea to sabotage Tommy's date with Trevor, so Tommy gave her a fake diagnosis with a familiar-but-vague childhood ailment, and a related disgusting milkshake concoction as a fake treatment to get even. Gastrocentesis in real life is not an illness, it’s a surgical procedure that involves puncturing a stomach to release excess gases.
  • Artistic License – Religion: A quick shot of Marjan's praying features mistake that could've been solved by simple research; Marjan doesn't wear a garb that covers her curvature alongside every body parts except for face and palms and her position before sujud (kneeling) is a typical rakooh position (bending waist forward with palms placed on each knee) while what actually comes before sujud is standing i'tidal (rising from rakooh, lifting palms facing forward on both sides of the head while saying "Sami' Allahu liman hamidah"). While details like leg stance, finger placements and some others may vary depending on interpretations, rakooh —> i'tidal —> sujud in that order is universal.
  • Affectionate Gesture to the Head: In "Friends Like These" (1.06) Zoe kisses Owen on the forehead before leaving.
  • Afraid of Doctors: Harry in "Awakening" (1.09), the boy who got a toy car stuck up his nose, though he's more afraid of hospitals. His mother went to the hospital when she got bad headaches and then one time she never came back. He associates it with death.
  • After-Action Patch-Up: After his Bar Brawl, Carlos helps TK clean up his face, in "Texas Proud" (1.03).
  • Almost Dead Guy: The astronaut in "Austin, We Have A Problem" (1.10), that gets through to Grace is dying of radiation poisoning due to the solar storm, he is able to stay alive long enough to speak to his wife and daughter, telling them both how much he loves them and he'll be watching over them.
  • Almost Out of Oxygen: In "Act Of God" (1.04), a man is stuck in a gun safe, he slowly begins to run out of air, while Grace has to talk his girlfriend through unlocking the safe.
  • Always on Duty: Averted, if only through passing references. Like real firehouses, Firehouse 126 has several different crews that man the trucks at different times. The main characters are seen leaving at the end of their shifts and there are other unnamed firefighters seen throughout the fire house.
  • Always Someone Better: Michelle had this relationship with her sister, Iris. Whatever Michelle would accomplish, Iris would do the same thing but better. In high school, Michelle won District for track, while Iris won State. Michelle became certified as an EMT and Iris went to medical school.
  • Anger Born of Worry: In "Texas Proud" (1.03), Judd blows up at TK and starts a fight, after TK disobeys a direct order on a rescue. Later Judd explains that seeing TK go under in the corn silo, reminded him of losing his original team.
  • Attention Whore: Marjan shows traits of this, as she is the first to do a dangerous rescue if there's a chance it'll be caught on camera and uploaded to social media.
    • Averted however when her hijab comes off in "Texas Proud" (1.03), Marjan is quite worried that moment was caught on camera.
  • Appetite Equals Health: Owen doesn't have much of an appetite in "Texas Proud" (1.03) after his chemo treatment.
  • Awesome by Analysis: Paul Strickland's specialty and the main reason he was tapped for joining the 126: in his interview its revealed that after rescuing someone from a burning building, he punched out a man revealed as the arsonist. Deconstructed as he reveals it to be a defense mechanism due to growing up trans as he needed to identify threats before they identified him. In the "Pilot" (1.01), he's able to determine how a mother crashed her car and where the doors would have come off, just by viewing the crash site. In "Yee-Haw" (1.02), he's able to figure out who and how the officer workers were poisoned within minutes, just by observing the area they were all sitting at.
    Paul: Growing up the way I did there was a lot of folks who wanted to hurt me so, I guess learned to figure out who they were before they figured out who I was.
    • The whole house does this when they are properly motivated, specially in “A Bright and Cloudless Morning” (3.18)— while Carlos and TK were figuring out their speech, they deduced the gist of it from the cheese and charcuterie types, the sparkling cider they had on the table, and the overall buildup to a toast. Except for Mateo, that is...

    • One of the reasons Owen wants Judd to come back to the fire house is because Judd has knowledge about local conditions and dangers that Owen lacks.

  • Poor Communication Kills:
    • In the "Pilot" (1.01), Fire House 126 was sent out to put out an out-of-control fire and were not warned that the facility housed a large quantity of explosive fertilizer. In addition, Judd was the only one in radio contact with dispatch so the warning was relayed to him first. He is too far away from the team to warn them in time and Judd ends up as the Sole Survivor.
    • This is lampshaded when various people warn Owen about keeping his cancer secret from family and friends. The longer he avoids telling them, the worse the situation will be when they find out on their own.
    • Just as Owen and Catherine's relationship is clicking in “Riddle of the Sphinx” (3.13), Catherine says her ex-husband Patrick will be stopping by who's "the spitting image" of Owen. Patrick comes by...a man in his 70s who's balding and a dull attitude. This causes Owen to mistakenly think that Catherine prefers older men, and later a raging argument on her "daddy issues". At which point, in comes Patrick, a handsome man who not only looks like Owen but shares the same interests. Turns out the Patrick Owen met earlier was Patrick Senior, his father. Owen tries to backtrack but it's too late and this misunderstanding (and his own insecurities) causes Catherine to storm out and later break up with him (although she has a tiny bit of blame for never mentioning her ex was Patrick Jr.).
  • Quicksand Sucks: A variation occurs in "Texas Proud" (1.03) with a corn silo. Corn stored in a silo can develop air pockets that can collapse and suck in a person standing on top of the corn. The victim then starts sinking. Rescue is difficult because the corn exerts a lot of pressure on the victim's body and if you try to pull the person straight out, you could literally rip him/her in half.
  • Racist Grandma: A call-out in "Yee-Haw" (1.02) is from an elderly woman, who calls the fire department on her neighbors who were using a BBQ pit that was spreading smoke into her yard. The neighbors, who turn out to be Hispanic, come out and the father of the family informs the 126 team that the woman is a racist who once called the cops on him during his daughter's birthday party just because they were waving around a baseball bat at a pinata. When Owen is about to make a citizen arrest on her for making a nuisance 9-1-1 call, the woman fakes having a heart attack. But when Marjan tries to give her CPR, the woman refuses because Marjan is Muslim (and presumably because she's a woman as well). She looks to Owen to do it, but he declines since he isn't CPR certified. She then asks T.K. to do it, but changes her mind when T.K. admits that he's gay. She then turns to Judd, but he declines as well (probably standing with his team in solidarity). To try and prove that she's not racist, the woman asks Paul, an African-American, to perform CPR on her. But when Paul admits that he's transgender, the woman finally gives up and tells Owen to arrest her.
    T.K: Cap, we can't take her to jail if she's having a heart attack.
    Owen: I know. Marjan, take her BP.
    Marjan: On it, Cap.
    Owen: Maybe give her some mouth-to-mouth.
    Ellen: No! Not her.
    Marjan: So maybe you're not having a heart attack?
    Ellen: I am. I definitely am! Can't you do it?
    Owen: Not certified.
    Ellen: Oh. How about him? [points to TK]
    TK: Sure, ma'am, but just so you know, I am a homosexual.
    Ellen: Oh.
    Judd: [Ellen points to Judd] No.
    Ellen: He can do it. [Ellen points to Paul] I told you I am not a racist! You're not a homosexual, are you?
    Paul: Oh, no, ma'am. But I am trans, though.
    Ellen: [Ellen puts her hands up] Take me to jail.
