When a young, down-on-his-luck director revives a forgotten opera in a crumbling, supposedly haunted theater, he discovers his biggest obstacle isn’t the leaky roof or his ex-girlfriend—it’s the charming, sharp-tongued ghost of a diva actress who died there 20 years ago. As rehearsals spiral into chaos and an exorcist shows up with unfinished karma of his own, the ghost and director form an unlikely bond—one filled with comedy, heartache, piano duets, and the wild backstage energy only theater kids and spirits could create. Together, they just might finish the show that was never meant to open—and give each other the final curtain call they’ve been waiting for.
