Italian documentary illustrating the devastation of the olive-growing flora in Apulia by the Xylella virus. In Apulia, a region in southeastern Italy, the most serious botanical pandemic of the century is underway: A quarantine bacterium, Xylella Fastidiosa, is killing millions of olive trees, disrupting the landscape, economy, and human relations. The Era of Giants narrates Giuseppe’s journey to his father’s land, in the Plain of the Monumental Olive Trees, where the epidemic is imminent. He will have to explain to the old farmer how their lives will be disrupted by this invisible bacterium, hitherto unknown in Italy.
