Natalie Portman throws herself completely into her role as a pop star in this odd character study that seems to have something to say about celebrity and tragedy, it's just not entirely clear what.
In the early 2000s, American teenager Celeste (Raffey Cassidy – Tomorrowland) barely survives a high school shooting. After her musical performance at the memorial service goes viral, a music manager (Jude Law) helps turn Celeste into a big-time singer.
In 2017, adult Celeste (Portman) is now a major star in the Katy Perry/Taylor Swift mode, and has a teenage daughter of her own, Albertine (also played by Cassidy).
Just before she is about to perform the first concert on a comeback tour, Celeste's music is linked with a terrorist incident. As the self-destructive Celeste tries to keep it together for her big performance, drama swirls around her.
Portman is pretty amazing in the lead role and especially impressive in the arena concert finale, in which she very capably sings songs written by acclaimed pop star Sia while also performing choreographed dance moves.
