The small town of Pacashau, Georgia, has fallen on hard times, but the community is counting on the Divinity Church Choir to lift their spirits by winning the National Joyful Noise Competition. The choir has always known how to sing in harmony, but the discord between its two leading ladies now threatens to tear them apart. Their newly appointed director, Vi Rose Hill (Queen Latifah), stubbornly wants to stick with their tried-and-true traditional style, while the fiery G.G. Sparrow (Dolly Parton) thinks tried-and-true translates to tired-and-old. Shaking things up even more is the arrival of G.G.’s rebellious grandson, Randy (Jeremy Jordan), who falls for Vi Rose's teenage daughter, Olivia (Keke Palmer).
