Based on the Tony-winning Broadway musical, this '60s-era story follows three young black female singers — Effie (Jennifer Hudson), Deena (Beyonce Knowles) and Lorrell (Anika Noni Rose) — as they try to cross over to the white-dominated pop charts. They're discovered at a talent competition by an ambitious manager (Jamie Foxx), who offers them the opportunity to become the back-up singers for headliner James "Thunder" Early (Eddie Murphy).
