Fan Casting The Sound of Music (1975)

In 1930s Austria, a young woman named Maria is failing miserably in her attempts to become a nun. When Navy Captain Georg Von Trapp writes to the abbey asking for a governess that can handle his seven mischievous children, Maria is given the job. His wife is dead, he is often away, and he runs the household as strictly as he did the ships on which he sailed in his glory days. The children are unhappy and resentful of the governesses their father keeps hiring and have managed to run each of them off one by one. When Maria arrives, she is initially met with the same hostility, but her kindness, understanding, and sense of fun soon draws the children to her and brings some much-needed joy into all their lives, and eventually, even the Captain is touched by her. Eventually he and Maria find themselves falling in love, even though he is already engaged to a Baroness named Elsa and Maria is still a postulant. The romance makes them both start questioning the decisions they have made. However, their personal conflicts soon become overshadowed by current events. Austria is about to be seized by Nazi Germany, and the Captain may soon find himself drafted into the German Navy and forced to fight against his own country. —Paraphrased from LOTUS73 on IMDb
