In the 1950s, Oscar Hammerstein is asked to write the lyrics to a musical based on the life of a woman named Maria von Trapp. He’s intrigued to learn that she was once a novice who hoped to live quietly as an Austrian nun before her abbey sent her away to teach a widowed baron’s sickly child. When the family was forced to flee their home to escape the Nazis, it was Maria who instructed them on how to survive using nothing but the power of their voices. Yet much of Maria’s life will have to be reinvented for the stage. But when Maria sees the script supposedly based on her life, she becomes so incensed that she sets off to confront Hammerstein in person. Told that he’s busy, she is asked to express her concerns to his secretary, Fran, instead. The pair strike up an unlikely friendship as Maria tells Fran about her life, contradicting much of what will eventually appear in The Sound of Music.
