More than twenty years after Racconto da un affresco (1940-1946), Luciano Emmer returns to Padua and the Scrovegni Chapel, home to Giotto's frescoes. He retains the structure of his first film (telling the story of Christ through the frescoes) and his principle of immersion in the paintings, but this time in color. He adds an introductory educational section (a historical presentation of the chapel and Giotto's frescoes) and a descriptive commentary that runs throughout the film.
