Céline Dion's heart goes on and on as she battles illness in the trailer for her new documentary

"I Am: Céline Dion" chronicles the beloved singer's battle with Stiff-Person Syndrome.

In December 2022, Céline Dion revealed she had been diagnosed with a rare neurological disorder, Stiff-Person Syndrome (SPS), that causes stiff muscles in the torso, arms, and legs. It also causes greater sensitivity to loud noises, which can trigger spasms and falls. As a result, the news came paired with a canceled world tour.

In her new documentary, I Am: Céline Dion, the beloved chanteuse chronicles her struggle to get back on stage to do what she loves: sing better than 99.9 percent of the people on the planet.

Directed by Oscar-nominee Irene Taylor, I Am is intended as a love letter, as well as a promise, to Dion's fans — a promise that she'll fight to return to performing for them again. The doc follows Dion through her daily life, from hanging out with her sons to touring her archive warehouse, as divas are wont to do.

Injected with Dion's quirky sense of humor, the film is described as "a deeply personal exploration of perseverance and inner strength, as well as daily battle and sacrifice. It is a celebration of the human spirit’s immense will to keep going, even when the only sense of self they’ve ever known has been lost."

Since announcing her diagnosis, Dion has, understandably, avoided the public eye — until this year's Grammys when she made a triumphant appearance to award the top prize of the night, Album of the Year.

"Thank you all," Dion said amid a standing ovation. "I love you right back. When I say that I'm happy to be here, I really mean it from my heart. Those who have been blessed enough to be here at the Grammy Awards must never take for granted the tremendous love and joy that music brings to our lives and to people all around the world."

In an interview with Vogue France last month, the "Set My Heart on Fire" singer declared her intention to learn to live with SPS to the best of her abilities.

"I have this illness for some unknown reason. The way I see it, I have two choices," the 56-year-old said. "Either I train like an athlete and work super hard, or I switch off and it's over, I stay at home, listen to my songs, stand in front of my mirror and sing to myself. I've chosen to work with all my body and soul, from head to toe, with a medical team. I want to be the best I can be."
