Professor Heines, an English art critic living in Tuscany in the 1930s with his family, realizes the incredible intellectual capacity of Guido, the son of a farmer and orphan of a mother. Stimulated by the scholar, the boy shows a great talent for music and, above all, for mathematics. When Heines returns to England for a short period of time, Guido is adopted by Mrs. Bondi, who owns the land where his father lives and works. (FILMAFFINITY)
