A brief synopsis of the episode, courtesy of NBC, follows. Be forewarned, there are spoilers in the description. "The big night is finally here," according to press notes. "Tom (Christian Borle) and Julia (Debra Messing) race against time to save the show, while Derek (Jack Davenport) makes a decision that will change the lives of Karen (Katharine McPhee) and Ivy (Megan Hilty) forever. Ellis (Jaime Cepero) reveals his true colors. But when he finally makes his move to save Bombshell, will it be for or against Eileen (Anjelica Huston)? In the midst of it all, another bombshell goes off – this one is in Karen and Dev’s (Raza Jaffrey) relationship."

As previously reported, the May 7 episode is titled "Previews" and is described as such: "Bombshell faces its first audience just as a major crisis hits Rebecca Duvall (special guest star Uma Thurman). The team of Tom (Christian Borle) and Julia (Debra Messing) scramble to fix the show when the first preview falls short, and Frank (Brian D'Arcy James) must adjust to the unwelcome return of Michael Swift (Will Chase) to his life. Dev (Raza Jaffrey) seeks reconciliation with Karen (Katharine McPhee), but explosive information about Ivy (Megan Hilty) lurks just beneath the surface." Jack Davenport and Anjelica Huston also star.
