ABC is gearing up to release a spinoff for Shonda Rhimes’ hit TV series, “Grey’s Anatomy.”

According to TV Line, the new show is expected to premiere on ABC sometime midseason. The spinoff to Ellen Pompeo’s hit series will follow the lives of a group of heroic firefighters who risk their lives in the line of duty. For the past 13 seasons, “Grey’s Anatomy” has featured a slew of firefighters who arrive at the hospital either to seek treatment or to send patients to receive the best care they deserve. According to Variety, Rhimes will also act as executive producer and will be working alongside Betsy Beers and showrunner Stacy McKee.

Meanwhile, the upcoming spinoff is rumored to air on ABC on Thursday nights right after “Grey’s Anatomy” airs at 8 p.m. EDT. “Grey’s Anatomy” will also return to the network for Season 14 in September. The hit medical drama has been renewed by the network for Season 15.

In the finale episode of the latest season of “Grey’s Anatomy,” Dr. Stephanie Edwards (Jerrika Hinton) risked her own life to help save a young girl while some parts of the hospital went down in flames. Even though she got out alive, Dr. Edwards expressed her desire to leave her practice later during her conversation with Dr. Webber (James Pickens Jr.).

Edwards’ storyline didn’t come as a shock to fans because Hinton’s departure from “Grey’s Anatomy” has already been reported several months back. The actress will be moving on to a different project that’s also being helmed by Rhimes.

Elsewhere in the episode, Owen Hunt (Kevin McKidd) found out that his sister, Megan, is very much alive. Meredith Grey (Pompeo) broke the news to Nathan Riggs (Martin Henderson). The latter was in a relationship with Megan and blamed himself for months and months on end, thinking that Megan is already dead. Meredith and Nathan’s relationship is just starting, but things can end for the two characters even before they begin with Megan’s arrival in Season 14.
