The “Greys’ Anatomy” spin-off “Station 19” finally has a full-length trailer. The show is set in Seattle in the firehouse just three blocks down from Grey Sloan Memorial Hospital. Much like “Grey’s,” it focuses on the firefighters from captain to the lower ranks and on their personal and professional lives. In the first episode we can already expect a surprise visit from Meredith Grey herself - and of course the show stars Jason Winston George, who fans will know as Ben Warren from "Grey's." Ellen Pompeo will make a guest-star appearance to welcome in the show. “Station 19” premieres March 22nd on ABC.
