Ruth, Esther and Chloe have been singing in harmony since before they could speak. Together they are The Salvations. Driven to success by their formidably ambitious mother, Vivian, they're soon the hottest jazz band in San Francisco. When the girls receive a once-in-a-lifetime offer from a renowned talent manager, Vivian knows this is the big break she has been praying for. She can see a different future for her girls, one that is a far cry from her childhood in racially segregated Louisiana. But somewhere between the grind of endless rehearsals on the rooftop and the glamour of weekly gigs at the Champagne Supper Club, the girls grow up and start to imagine a life beyond their mother's reach. As Vivian's hold on her family begins to weaken, she must confront changes in The Salvations, in the San Francisco neighbourhood she has made her home, and even in her own family.
