A woman leaves an Austrian convent to become a governess to a Naval officer widower. Maria had longed to be a nun since she was a young girl, yet when she became old enough discovered that it wasn't at all what she thought. Often in trouble and doing the wrong things, Maria is sent to the house of a retired naval captain, named Captain Von Trapp, to care for his children. Von Trapp was widowed several years before and was left to care for seven 'rowdy' children. The children have run off countless governesses. Maria soon learns that all these children need is a little love to change their attitudes. Maria teaches the children to sing, and through her, music is brought back into the hearts and home of the Von Trapp family. Unknowingly, Maria and Captain Von Trapp are falling helplessly in love, except there are two problems, the Captain is engaged, and Maria is a postulant!
