Stefano, a young restorer is commissioned to save a fresco representing the suffering of St. Sebastiano. The fresco painter was Legnani, and the fresco is his last work. Legnani apparently was mentally disturbed. He was used to paint people close to die or in agony. These facts together with the strange atmosphere that surround this village near Ferrara, in the north of Italy, contribute to put Stefano in a nightmare reality. Soon reality will change into horror.
