Detroit, 1968. The Motown sound is sweeping the nation. Girl groups are hotter than ever. Over their mother's (Whitney Houston) objections, three beautiful sisters -- Delores (Tika Sumpter), Sister (Carmen Ejogo) and Sparkle (Jordin Sparks) -- are taking the local music scene by storm. But their dreams are bigger than Detroit. Their manager, Stix (Derek Luke), is just as ambitious and will do whatever it takes to make it to the 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 the natural headliner of the trio, yet her complicated personal life threatens to overshadow her talent; Delores has her sights set 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?
