Last May, ABC announced that showrunner Stacy McKee and Shonda Rhimes, creator and head writer behind the hit show Grey's Anatomy, will be spearheading a new show based off the long-running medical drama.

More details about the spin-off, including the plot line and cast, emerged in October. At the time, the show was untitled, but it was confirmed that the story will revolve around the professional and personal lives of firefighters at Station 19, located just three blocks from Grey Sloan Memorial.

Ellen Pompeo, who portrays Dr. Meredith Grey on the original series, will co-executive produce the show alongside Rhimes. At the time, it was unclear if her character will crossover, but then it was revealed that at least one Grey's Anatomy series regular would be taking on a lead role on the new show.

Jason George, who plays Dr. Ben Warren, officially left the flagship show to join the firefighting world. George joins Rosewood alum Jaina Lee Ortiz, who will be the show's leading lady, Andy.

In late January, ABC teased fans with more details about the upcoming series, which has officially been titled Station 19. The 10 episode season will air its pilot  in March, and now, after much anticipation, the network has finally released the first trailer.

Viewers were treated to a red-hot sneak peek of Station 19 during Thursday's episode of Grey's Anatomy.

The clip also hinted at the fact that George's Ben will be playing an even bigger role than we expected because it looks like the Andy's dad, Captain Pruitt Herrera, will be stepping down from his position at the firehouse.

We also finally get confirmation that Meredith and Grey Sloan Memorial will be featured on the show, but we don't know to what extent.

Based on the trailer alone, fans can expect the upcoming spin-off to be filled with a lot of drama, romance, and heart-wrenching moments. However, McKee said that fans should not to expect Station 19 to flow exactly like original.

"It'll be similar and different," McKee said at the 2018 Winter TCA Press Tour. "It was a priority for me in thinking about this as a Grey's Anatomy spinoff that it works hand-in-hand with Grey's and was similar in both tone and intensity and humor and heart."

She added, "But there's also an added element to this show that a hospital setting doesn't allow which is that most of our characters are on site and in the middle of action sequences, so there's a certain level of adrenaline and energy that comes with that that you don't necessarily find in the same way at Grey's. You find it in different ways. So, to me, it's very similar in tone and spirit, but also a little bit different as well."

Station 19 will premiere on Thursday, March 17 at 9.pm. on ABC.
