Late 1930s, Austria. Postulant Maria is not considered nun material by her superiors and is given a temporary assignment caring for the seven children of Captain Von Trapp, who's become an unhappy martinet since his wife's death and since his beloved Austria seems to be succumbing to the Nazi regime. While the children attempt to drive their new governess crazy, Maria wins over Liesl, the oldest, when she promises not to tell the captain about the girl's love for delivery boy (and Nazi sympathizer) Rolf. Maria then completely charms the other children when she teaches them to sing. When the captain's friend Max, a music impresario, hears them, he books them into a nearby festival. Although the captain is reluctant to allow his children to perform, his fiancee Elsa encourages him to let them. The captain's inability to see the Nazi reality scares Elsa away from marriage--but the captain has slowly been falling in love with Maria because of the wonderful job she has done with his children. They marry but do not quite live happily ever after. The captain turns down a commission with the Nazis and becomes their enemy. He, Maria, and the children try to escape after appearing at the festival. They're caught by Rolf, but because of his love for Liesl, he allows them to escape. They are traveling over the mountains to Switzerland at the play's end. Synopsis (c) Peter Filichia
