The story is set in Catania (Sicily) where Ciccio, a ten years old boy, escapes from school, with two friends of his, Sasha e Piero, to run and reach a sea port where they meet Turi, an old fisherman. The children ask Turi to bring them to the so-called 'cave of faces'. It's a sea lava cave, on its rock some stone faces appear. In the cave there's also a secret to discover: the ghost of an ancient little princess that will bring the children in her time and in her sad story. Will the children be able to free the ghost from her captivity? In Sicilian dialect the word SDRVGD'T is the imperative form of the verb 'sdrivigghiari' that means 'to wake up'.
