Just want to fill you in on the first 7 hours of Wagner's opera which is on PBS television directed by James Levine.
It seems there is this little gnome guy who is feeling horny and wants to hump one of the three Rhine maidens. These maidens are supposed to be guarding some magic gold. They think the little guy is funny and lead him on and then disappoint him and laugh at him. He is getting real pissed and decides to steal their gold, which if you renounce love and make a ring from it you will get all sorts of powers. He ain't getting laid anyhow so what's to lose and he steals the gold and makes a ring from it.
Now Wotan who is the chief God steals the ring and uses it to pay the giants to build him a castle called Valhalla. In the meantime there is a half god called Sigmund who is Wotan's son by a mortal woman he humped and Wotan loves him very much. Sigmund gets himself in trouble by humping his sister who is married to someone else and knocking her up. Wotan wants to protect his son but Frikka his wife who is the protector of marriage says nothing doing, That incestuous bum has to die. So Wotan tells his favorite daughter called Brunhilde to not protect Sigmund in the coming fight. Brunhilde is a Valkyrie and along with her sisters all daughters of Wotan from humping other than his wife. The job of the Valkyries is to pick up fallen heroes from battlefields and bring them to Valhalla where they are guards and have luscious dolly birds to serve them.
Well Brunhilde feels sorry for Sigmund and protects him until Wotan stops her and Sigmund is killed. Now Wotan is real pissed with her and condemns her to be mortal and serve a mortal man as his wife. She pleads with him to at least let the man be a hero. He gives in and puts her to sleep and surrounds her with fire so only a fearless hero can get to her.
this is where it ends but you know it will be Siegfried, Sigmund's bastard son who will eventually hump her. That will fill you in up to now. Tune in PBS for the exciting final scenes.
This is a very high class story and Mark Twain said about it that "it's better than it sounds"
It's easy to see why it was Hitler's favorite.
