Back from a successful run in Boston, Eileen, Julia and Tom are blindsided by both personal and professional obstacles as they seek to take "Bombshell" to Broadway. Karen consults her new mentor, Broadway star Veronica "Ronnie" Moore, as she finds herself on the brink of fame, but her success may come at cost to Ivy. A new talent is discovered in an unexpected place. Meanwhile, Derek copes with a damaging accusation.

The creative team behind Bombshell attempt to repair their reputations and mount the show following legal allegations about the source of financing for the show by Eileen Rand and sexual harassment charges levelled at director Derek Wills by several women. Bombshell star Karen Cartwright encounters resistance when she tries to aid new composing team Jimmy Collins and Kyle Bishop working on their first musical.

Julia's fears increase when Tom airs his suspicions of Peter. Jimmy and Kyle confront their own crisis of confidence as "Hit List" is read for the first time. Meanwhile, Ivy realizes her triumph might not be all she hoped when she meets her new co-star, Terry Falls, and Karen wonders if she can trust Jimmy.
