Sister Kenny.

Elizabeth Kenny (Rosalind Russell) returns from nurse school in Brisbane, Australia to her home in the bush of Queensland with the head doctor at the nearest hospital. Three years later, Sister Kenny visits a young girl, Dorrie (Doreen McCann), who is bedridden. She wraps Dorrie in hot cloth, and the girl eventually fully recovers, as do five other cases of infantile paralysis that Sister Kenny finds and treats.
