Anna's father, Guglielmo, holds Roberto responsible for Anna's death and calls upon the Villi to take vengeance on Roberto (Aria: "Anima santa della figlia mia"). The Villi call upon the ghost of Anna and lure Roberto into the forest. Roberto, now penniless and abandoned by the seductress, returns when news of Anna's Death reaches him. Hoping that he will be forgiven the Villi stalk Roberto as he mourns the loss of the days of his youth (Aria: "Torna ai felici dì"). Roberto then finds the one last flower left alive in the winter and tries to find hope that Anna lives but is repelled by the Villi when he ties to knock on the door of Guglielmo's house. Roberto then tries to pray for forgiveness but finds he cannot because of the curse put upon him by the Villi. As Roberto curses his fate Anna appears to him and tells him of the suffering that she had to endure. Roberto begs for forgiveness and he too feels the pain of Anna burning in his heart. But Roberto is not forgiven and Anna calls upon the Villi, who curse Roberto with cries of "traitor." There, the Villi and Anna dance with Roberto until he dies of exhaustion at Anna's feet.
