This documentary spans the life and career of Spanish soprano Montserrat Caballé, one of the very best ever - a legend, arguably the "queen" of all divas still singing. In locations throughout the world where Ms. Caballé sang, we hear interviews with Ms. Caballé, her family, and by opera and music giants like Claudio Abbado, José Carreras, Giuseppe Di Stefano, Plácido Domingo, Renée Fleming, Dame Joan Sutherland, and Zubin Mehta, also appearing often in clips showing joint collaborations. Of these, the film includes passages from Caballé's most acclaimed roles such as "Norma"', "Tosca" , "Turandot" and her earliest recorded live performance (1966) as "Anne Boleyn," in addition to poignant and powerful live concert duets with fellow Spaniards Plácido Domingo, Juan Pons, and José Carreras.

Mario, a young and uprooted Menorcan fisherman, falls in love with Irene, a Barcelona socialite who spends her holidays on the island with her young daughter. After the ambiguous initial relationship, victim of the rumors and slander, she decides to leave him. Mario, unable to resign himself, follows her to Barcelona, where he finds her imprisoned in a marriage lacking in love, in which her husband, a rich and powerful industrialist related to shady business, holds her under the threat of separating her from her daughter.
