Documentary about Dame Joan Sutherland, one of the greatest operatic performers of the late twentieth century, who died in October 2010. Shy and lacking in confidence, she had sung unnoticed at Covent Garden for seven years after arriving from Australia, but over the course of twelve months was transformed into La Stupenda. With a focus on the two roles - Lucia di Lammamoor and Alcina - that launched her, the film features interviews with Dame Joan, Richard Bonynge, Franco Zeffirelli, Placido Domingo and Luciano Pavarotti.
