chunk: The film opens with violinist Roberta Guaspari having been deserted by her US Navy husband and feeling devastated, almost suicidal. Encouraged by her mother, she attempts to rebuild her life and a friend from student days recommends her to the head teacher of a school in the tough New York City area of East Harlem. Despite a degree in music education, she has little experience in actual music teaching, but she's taken on as a substitute violin teacher. With a combination of toughness and determination, she inspires a group of kids, and their initially skeptical parents. The program slowly develops and attracts publicity.
