Detroit, 1968. The Motown sound is sweeping the nation. Girl groups are hotter than ever. Over their mother’s objections, three beautiful sisters— Delores, Sister and Sparkle— are taking the local music scene by storm. But their dreams are bigger than Detroit. Their manager, Stix, is just as ambitious and will do whatever it takes to make it big time, even if it means using the girls— and his love for Sparkle— as the foundation of a new musical empire.

Behind the music and lights, the recording industry is a ruthless and unforgiving place, just as Mama had warned her girls. Sister, with her good looks and voice, is a natural headliner for the trio, yet her complicated personal life threatens to overshadow her talent; Delores has her sights set out on a different kind of life outside the spotlight; and young Sparkle must push past her deepest fears if she is to fulfill her destiny— does she really have what it takes to go all the way?

Riveting and soul-stirring, this timeless tale reminds us of the unbreakable bond between family, the high price of fame, and what can happen when we dare to show the world how brightly we can sparkle.
