Ballet Shoes (1975)

Pauline, Petrova, and Posy Fossil live with Sylvia Brown, their guardian. Money is tight and as the story opens, three boarders - a garage owner, a retired English professor, and a dance teacher - come to stay. Theo Dane, the dance teacher, has the girls accepted at her school by the formidable Madame, and the three go on the stage to help raise money. Each discovers her talents - Pauline as an actress, Petrova in fixing engines, and Posy as a dancer.
