Rodgers and Hammerstein's The Sound of Music is a 1965 musical film. The film is based on the Broadway musical The Sound of Music. The musical originated with the book The Story of the Trapp Family Singers by Maria von Trapp.
In Salzburg, Austria, Maria, played by Andrews, is studying to become a nun but is not sure if convent life is right for her. She is sent from her abbey to be the governess to seven children of a widower naval commander, Captain Georg Ritter von Trapp. Maria and the Captain immediately disagree on the way the children are treated; the Captain has been raising them according to the principles of military discipline, while Maria wants them to enjoy life as children while they can.
The children, mischievous and initially hostile to Maria, eventually come to love her when she introduces them to the pleasures of music and singing. Once the Captain discovers this, he feels very remorseful for his rigidity. He apologizes to Maria for being so strict with the children, asks her to stay for a while, and seeks to enjoy living himself. One of the Captain's friends, Max Dettweiler, tries to convince the Captain to let the children perform in his concert. Maria finds herself falling in love with the captain, who is engaged to Elsa Schraeder, a very wealthy baroness. The Baroness becomes jealous of Maria and convinces her to leave during a grand party at the house, by exploiting Maria's inner conflict about becoming a nun and her discomfort at the Captain's obvious affection towards her.
Although the Captain announces his intention to marry the Baroness Elsa, she does not have good rapport with the children. After a talk with the Mother Abbess, Maria decides to return to the Trapp family. Upon Maria's return, the Baroness realizes the Captain is in love with Maria and decides to leave for Vienna after the Captain himself makes it clear that he is not in love with her and that a marriage between them would not work. Afterwards, the Captain and Maria reveal their feelings for each other and finally wed.
