Ahead of next month's premiere, NEON shares the second official trailer for new film, Vox Lux, starring Natalie Portman. Portman portrays Celeste, a now 31-year-old pop singer whose better days are seemingly behind her.

Vox Lux is told in two parts, beginning in 1999 with the story of two teenage sisters, Celeste (played by Raffey Cassidy) and Eleanor (played by Stacy Martin), who after surviving a school shooting, write and perform a song about the horrific experience. This ultimately launches Celeste into stardom, until at the age of 31, she finds herself struggling in her once prolific career.

Press play above to watch the new trailer for Vox Lux, complete with an original song by Sia, as the movie is due in theaters in New York and Los Angeles on December 7, followed by a nationwide release on December 14.
