1982 drama/musical “Sister, Sister” starring  Diahann Carroll, Rosalind Cash, Irene Cara, Paul Winfield,Diana Douglas and Robert Hooks.

Maya Angelou’s story of the family stresses that occur when an older sister (Diahann Carroll) attempts to maintain a home, left by her revered father, in an ultra-moralistic way (regardless of the fact that she is secretly having an affair with the married preacher). Nevertheless, her uptight need to maintain a sense of propriety of course goes against the wishes of her much younger sister (Irene Cara) who, as an accomplished ice skater, is striving for her own independence. And if this isn’t enough, into it is suddenly thrust a third sister (Rosalind Cash), who is a single mother with a pre-teen son, who “comes home” with her boy after living for years in the ghettos of Detroit. And because she is the complete antithesis of her older sister in morals and deportment, she immediately sides with her younger sister against the strictures set down in the home.
