Luisa Miller
From the San Francisco Opera website:
A father’s betrayal. A daughter’s sacrifice. Longing only for love, a brave young woman sacrifices her own happiness in a desperate attempt to save her father’s life. Revered for its masterful depiction of intimate emotions, Verdi’s swiftly moving tragedy explores the forbidden passion between a peasant girl and a nobleman and the plotting of two ruthless men determined to tear them apart.
