When her daughter vanishes, a district attorney who has spent her career fighting for other families must fight for her own.

When her daughter goes missing, a driven district attorney launches a desperate search, retracing the girl’s last known steps. As the night unfolds, she’s joined by her ex-husband, a police officer, whose presence pushes her forward. The investigation escalates into a confrontation with a dangerous man connected to her current case.

But as the pieces fall into place, the truth behind her ex’s presence —and the cost of her relentless focus— becomes clear. In the aftermath, she must reconcile guilt, duty and heartache as she finally lets go of the past.

Named for Debussy's timeless composition, Clair de Lune reflects the film's emotional rhythm— moving from quiet intimacy to mounting suspense before arriving at a deeply human conclusion. Like the music itself, this film reminds us that love can endure even in our darkest hours.

Clair de Lune becomes more than a suspenseful race against time. It's a story about family, forgiveness, and what it truly means to be present for the people we love.

Clair de Lune begins with a universal fear, but it's ultimately about something even more familiar: how the very things we dedicate ourselves to —our careers, our responsibilities, even our sense of purpose— can quietly pull us away from the people we love most.

At its core, this is an emotional thriller about family, justice, and second chances. We believe great stories entertain us, but the best ones endure by surprising us.

We're making Clair de Lune because we believe

the most powerful thrillers don't just keep us guessing,

they remind us what's truly worth fighting for.
