Produced by the Greek National Opera using unreleased musical recordings and archive footage, this film reveals the untold story of Maria Callas, Opera's greatest Diva.

This meticulously researched film reveals how Callas’ strength, tenacity and inner demons were first forged by life in wartime Athens, where she worked as a spy for the British Government and first became a stage sensation. In 1957, she returned as Callas the Diva and global superstar, to finally reconnect with the nation that made her.
