La sonnambula
Amina is engaged to Elvino in a Swiss village. Count Rodolfo, the long-lost son of the former lord, returns and recognizes the area. That night, Amina sleepwalks into his room; Rodolfo leaves without disturbing her, but villagers find her there and Elvino rejects her as unfaithful. Elvino plans to marry Lisa instead. Rodolfo explains that Amina is a sleepwalker, but Elvino demands proof. As Amina crosses a mill bridge in her sleep, she relives her grief at his rejection and safely reaches the other side. Elvino restores her ring, she wakes, and they reconcile.
