In 1925, the maestro Leopold Goronoff (Philip Dorn) discovers the talent of the young pianist Myra Hassman (Catherine McLeod), the daughter of an old friend called Frederick (Felix Bressart) and takes her from Philadelphia to Carnegie Hall and on to the capitals of Europe. Myra is caught between the love of her teacher, who becomes increasingly abrasive towards her the better she plays, and of her childhood friend George who waits for her loyally on his farm back home: “I’ve always loved her.” Apart from the omnipresent love, in this costly mini-major Republic Pictures production, the opulent and colorful sets shot in three strip Technicolor and the music - more precisely Rachmaninov’s Piano Concerto No. 2 in C minor, Op. 18 - play a key role. The 14-minute solo concert scene was played by Arthur Rubinstein, who instructed actors during the playbacks.
