Teresa Stratas is one of the great singing actresses of today, having appeared on all the great opera stages in all the great roles.

Now, in her mid-forties, she is still the centre of attention around the world. The story of her life is determined by extreme emotions, by torment and triumph, and this life between the light and the dark has been investigated by Harry Rasky with great care and tenderness. It is a film for opera lovers, with excerpts from Salome, The Zarewitsch and La Boheme, as well as a detailed account of Miss Stratas' rise to fame, including her relationships with people as different as Franco Zeffirelli and Mother Theresa.
