Act I. By the Rhine. A king wants to get married, and also to give

his sister in marriage. Hagen, the king's wicked brother, advises him to marry Brünnhilda and to give his sister to Siegfried. Siegfried appears; they give him a drugged draught, which makes him forget all the past and fall in love with the king's sister, Gutrune. So he rides off with Gunther, the king, to get Brünnhilda to be the king's bride. The scene changes. Brünnhilda sits with the ring. A Valkyrie comes to her and tells her that Wotan's spear is broken, and advises her to give the ring to the Rhine nymphs. Siegfried comes, and by means of the magic helmet turns himself into Gunther, demands the ring from Brünnhilda, seizes it, and drags her off to sleep with him.
