The Final curtain
The rule of the Gods is over, the age of the humans is dawning - or it will be if Hagen, the son of the dwarf Alberich has anything to do with it. A mighty battle for the future of the wold, for love and for honor unfolds as The Ring Cycle reaches its crashing - and unforgettable - finale.
Gotterdammerung
Having won his beloved Brunnhilde, Siegfried gives her the Ring of Power as a token of his love before seeking out new adventures. But his course is interrupted by the callous siblings Gunther and Guntrue and Hagen, son of the cunning dwarf Albericht, who maliciously trick him into marrying another, sending Brunnhilde into utter despair.
Too late, Siegfried realises the the deception he has been party to, leaving Brunnhilde no option but to make one last attempt to save her happiness, by restoring the accursed Ring to the bereft Rhinemaidens, thus restoring the natural order of the universe - ending the reign of the Gods forever.
