Set in the rural Midwest during the 1970s, Black Hollow follows Jessica, an innocent young girl sheltered by small-town faith and her worldly friend Helen, whose rebellious streak leads them both into danger. When the two sneak out one foggy night, they wander to a forgotten churchyard, an isolated place where sacred ground conceals something unholy. As darkness descends, Jessica's search for belonging turns to horror, forcing her to confront the evil that thrives beneath the surface of the American heartland.
