Find out how Siegmund and Sieglinde’s forbidden love causes Brünnhilde’s downfall. The mysterious hero Siegmund finds shelter in the strangely familiar arms of a lonely woman named Sieglinde. Their forbidden love leads Wotan’s daughter, the warrior maiden Brünnhilde, to defy morality and intervene on behalf of the hero. Brünnhilde’s transgression forces her father to choose between his love for his favorite daughter and his duty to his wife, the formidable goddess Fricka. Overcome with grief, Wotan takes away Brünnhilde’s godlike powers and puts her to sleep on a mountaintop, surrounded by a ring of magic fire that can be crossed only by the bravest of heroes.
