Ryan Murphy has just responded to Fox's 911 call.

The network is near a deal for a straight-to-series drama from Murphy and his frequent collaborator Brad Falchuk, The Hollywood Reporter has learned. American Horror Story's Angela Bassett is set to star in the series.

Titled 911, the drama is a procedural about 911 operators and the calls that come through the emergency telephone number, with stories inspired by calls. Additional details are being kept under wraps.

The drama, in the works for months, is said to be 13 episodes and slated for midseason. Murphy and Falchuk will both exec produce via their 20th Century Fox Television-based production companies.

911 arrives as Murphy and Falchuk are awaiting word on the future of Fox anthology Scream Queens, which is not expected to return for a third season. (Several co-stars, including Lea Michele, have already moved on to other shows.)

The drama marks the latest collaboration for Murphy and Falchuk at Fox, where they produced musical phenomenon Glee. The frequent collaborators are also working on new seasons of FX anthologies American Horror Story and American Crime Story and have ongoing drama series Pose in the works for the cabler. The latter, set in the 1980s, explores life and society in New York including the rise of the luxury Trump-era universe, the downtown social and literary scene and the ball cultural world.

Murphy additionally is casting season two of FX anthology Feud.

The drama extends Murphy and Falchuk's relationship with Bassett, who starred in four seasons of American Horror Story (Coven, Freak Show, Hotel and Roanoke). It's unclear if she's part of season seven of the franchise, as those details continue to be kept under lock and key.

Fox and producers 20th Century Fox Television declined comment. A formal announcement is expected to come as early as Monday as part of the network's upfront presentation to advertisers.

Murphy is repped by CAA; Falchuk is with WME and Gendler & Kelly; Bassett is repped by Gersh, Lighthouse Entertainment and Fox Rothschild.
