Viktor Taransky (AL PACINO) is a Hollywood director who's been plagued by recent bad luck. Not only have his last three films flopped, but also his latest one starring Nicola Anders (WINONA RYDER) has run into a major snag. Viktor has no problem with her co-star, Hal Sinclair (JAY MOHR), but the vain and pampered actress is driving him crazy with her constant personal demands.
She eventually quits and threatens to sue if any of her footage appears in the film, resulting in studio head
Elaine Christian (CATHERINE KEENER) pulling the plug on the project and firing Viktor. That only adds salt to the wound since she's his ex-wife with whom they have a teenage daughter, Lainey (EVAN RACHEL WOOD).
Viktor gets a break, however, when the ailing Hank Aleno (ELIAS KOTEAS) approaches him with a solution to his problem. It seems that he's developed a software program - Simulation One or "S1mOne"- that will allow for the creation and inclusion of a realistic-looking but completely computer-generated performer into his unfinished film.
Nine months later, Viktor has completed his work with "Simone" (RACHEL ROBERTS) having replaced Nicola. Not only is the film a hit, but the press and public are also fooled into believing the "actress" is real. She quickly becomes an overnight sensation and everyone wants a piece of her, including tabloid reporters Max (PRUITT TAYLOR VINCE) and Milton (JASON SCHWARTZMAN) who work the hardest at uncovering the story behind the new star. As they do so, Viktor must then deal not only with maintaining his secret, but also his new actress' increasing popularity and stardom.
