Two desperate and talented performers — Ivy (Megan Hilty), a Broadway veteran looking to move beyond the chorus line, and Karen (Katharine McPhee), a Midwestern girl stuck waiting tables — fight to star in a musical based on the life of Marilyn Monroe.

To get the lead role in the new musical drama Smash, they'll have to win over a writing duo that's out for one more hit (Debra Messing, Christian Borle), a producer in the midst of a messy divorce (Anjelica Huston) and a director (Jack Davenport) with an ego bigger than the Big Apple.

"I have always had an interest in theater," explains executive producer Steven Spielberg, "but it's that creative process — what goes on before the curtain even goes up — that really fascinated me."

The result is a behind-the-scenes look at musical theater with a few soulful show tunes for good measure (think: Glee meets The West Wing). And in a meta twist, the Marilyn production they're putting together on the show may one day be staged as a reallife Broadway musical.
