A Sister's Promise (1940)

A family comprised of a father, mother and three sisters lives in a posh area. The father is a doctor who has to join the army and work at war. The four remaining women have to take care of themselves. The eldest sister is calm and lady-like. The middle sister (played by Hara Setsuko), in contrast, is active and contemporary. She aspires to be a physician too. The story is based on Little Women by Louisa May Alcott.
