An artistic, human, public and production clash which opposed Roberto Rossellini, Anna Magnani, Ingrid Bergman against the young aristocrats of Panaria, "prompters" of the film Stromboli and producers of the competing film Vulcano. 80 year-old Francesco Alliata, Prince of Villafranca and Duke of Salaparuta, the last survivor of the Panaria film, tries to reconstruct, with photos, documents and archive films, that adventurous season of 50 years ago.
