"Parsifal" was Richard Wagner's last opera. Its story centers on the search for the Holy Grail, although it's actually a spiritual voyage into the protagonist. To learn more about the Holy Grail, Gener travels to three different locations: Montségur, Valencia, and Montserrat Monastery.

Gener heads to Bayreuth, the hometown of Richard Wagner, the composer of the most ambitious operatic saga in all of musical history, "The Ring of the Nibelung". This tetralogy is made up of four operas: The Rhine Gold, The Valkyrie, Siegfried and Twilight of the Gods. Gener touches on all of them as he visits the Autostad automotive plant, walks the stage at the Bayreuther Festspielhaus (the theatre designed by Wagner himself), and converses with one of the most renowned experts on the composer.

Gener heads to Cadaques on the Costa Brava to talk about a great love story, of a love beyond death: what Tristan and Isolde felt for one another. Again, Gener interviews anonymous people who have experienced great love stories like the protagonists of this particular opera, and who act as a counterpoint to show that love is more powerful than death.
