While vacationing in Italy, Nick Morell, son of John Morell, a famous English philosopher and amateur musician and his wife Catherine, becomes friendly with young Guido, and Morell discovers the boy has an extraordinary instinct for orchestration and a phenomenal music memory. A neighboring couple, Signor and Signora Boudini become aware of the boy's talents, and she appeals to his parents to let her educate him musically. Torn by their love for their son and, they feel,the duty to let the world hear his talent, they consent.
