In the pilot of Smash we are introduced to Tom Levitt and Julia Houstona song-writing duo who had planned on taking a break from the business of Broadway but, find themselves drawn back in when they get the desire to produce a musical based around the life of Marilyn Monroe. When a demo of one of the tracks goes viral the project attracts the eye and ear of tenacious producer Eileen Rand and, although causing a conflict that of director Derek Wills. But the biggest and most important task is to find their Marilyn after, auditioning a range of girls they whittle it down to two but, who do they go for. Ivy Lynn a veteran of the stage who wants to break away from the chorus line to get her break as a lead or Karen Cartwright a fresh talent who is trying to follow her dream of becoming a star.

Ivy and Karen jump through hoops for the brilliant but temperamental director Derek Wills as they pursue the role of a lifetime. Meanwhile, Julia and her husband Frank, are frustrated by the red tape of an international adoption process, and Eileen fights to finance her new musical in the midst of an acrimonious divorce.

The search begins for a Joe DiMaggio to play opposite Marilyn - but everyone's first choice, Michael, has a secret. Karen returns to Iowa for a baby shower and must decide what she wants for her future. Eileen begins rounding up investors - but ex-husband Jerry may already have poisoned the well.

The team deals with the workshop's after-effects; Derek asks Karen to help him steal the show from Tom and Julia; Eileen's daughter's surprise visit forces her to deal with her ex-husband.

Karen finds herself seduced by the glamorous life of new BFF Rebecca Duvall -- but can Rebecca be trusted? What will Karen's ascent mean to her relationship with Dev? And will Rebecca drive Derek insane? Eileen introduces new beau Nick to ex-husband Jerry, while Julia panics when her son Leo goes missing.

Tom and Julia work to save the show, while Derek makes a decision that will forever change Karen's and Ivy's lives; Ellis tries to save the show.

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.

Derek calls in help for a special event, but Jimmy's pride might get in the way of a huge opportunity Karen orchestrates for him and Kyle. Peter challenges Julia's pride as they continue to work together. Meanwhile, Ronnie struggles to assert her independence from a powerful mother, as Eileen finds herself at a moral crossroads with huge ramifications for "Bombshell."

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.

Derek and Karen reach a turning point, so one of them makes a tough decision. Meanwhile, problems emerge in Jerry and Eileen's partnership; complications arise at the "Hit List" debut at the Fringe Festival; and Ivy attempts to save her and Terry's show.

New circumstances give rise to conflicts as Karen, Tom, Julia and Derek adjust to their new surroundings. Tensions at "Liaisons" are also coming to a boil, ensuring that the show will find its place in Broadway history. Meanwhile, Eileen may have found the key to saving "Bombshell" with the help of her daughter, Katie.

Tom takes legal measures to dissolve his partnership with Julia. Karen contemplates beginning a sexual relationship with Derek following her fall-out with Jimmy. But all comes to a screeching halt with the news of Kyle's death. The one person who isn't yet is Jimmy, who is no where to be found. Derek and Scott have to figure out what to do about this evening's show. Julia wants to do something special to remember Kyle which she hopes will be supported by the Broadway community despite Kyle not yet having done anything on Broadway.

It's a crucial moment for both shows as Tony nominations loom, but keeping your eye on the prize can be hard. As Tom crosses an influential Tony voter and Ivy copes with some very distracting news, Derek's past has repercussions for the entire "Hit List" team.

On Tony night, the awards might not provide the answers everyone is looking for. As Jimmy faces a final reckoning, Tom, Julia, Derek, Karen, Ivy, and most of all, Eileen wait to see if the ceremony will confirm their place in the Broadway pantheon once and for all.
