Three friends sneak into an old theatre for a night of daring exploration, only to uncover the chilling legend of Elaine Evans—a glamorous 1920s starlet who died mid-performance on opening night of A Doll’s House. Ever since, a single ghost light has burned onstage to give Elaine her nightly “performance” and ward off darker spirits. But when the girls are separated in the twisting backstage shadows, they realize too late that the light is the only thing keeping Elaine’s restless spirit at bay. As the theatre closes in, their only hope for survival is to find each other… and stay in the light.
