40 years after her death, Maria Callas is still one of the greatest opera singers of the 20th century. Thanks to her unique voice timbre and her talent for tragedy, she was able to play her characters with great intensity.

In 1947 she meets her mentor and future husband Giovanni Battista Meneghini. But it was 10 years later, on September 3, 1957 that her life changed: she was introduced to a rich shipowner named Aristotle Onassis. Then begins a tumultuous love story which will last for 9 years.

In 1960, La Callas' career begins to decline. Health problems gradually cause a decline in her voice which will lead her to stop her career at age 40.

Nevertheless, the Diva will remain the one who changed the lyrical art during 20th century both with her rare musicality and great virtuosity.
