A secret love unites the seeress Norma with Pollione, the Roman proconsul, by whom she has borne two children. But Pollione has grown tired of the aging druidess and has fallen in love with Adalgisa, a young temple virgin. Despite Adalgisa's piety and virtue, she agrees to flee to Rome with Pollione. Adalgisa innocently tells Norma of her love, and Norma curses Pollione for his treachery.
Act 2
Norma is about to kill her children, but her love for her children finally confides them to the care of Adalgisa. When Pollione comes to take Adalgisa from the temple, Norma denounces him and he is seized by the Druids, after having refused to give up Adalgisa. Norma proclaims herself equally guilty with him. The pyre is lighted, and ascending it, Norma dies with her lover.
