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.

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.

After Leigh Conroy joins the cast of "Bombshell," Tom finds himself struggling to diffuse the years of tension between her and Ivy. Jimmy and Karen's connection is threatened by both Ana's newfound success and an unexpected visitor. Derek learns more about Jimmy's past just as the public sees their first piece of "Hit List."
