Archaeologists digging in Sicily uncover a sealed convent where five nuns were crucified in the 15th century. This discovery unleashes an ancient evil and bizarre murders begin to take place. Unfortunately, that's about it as far as the plot goes. Even by Fulci's standards, "Demonia" is slow and pondering, with many scenes taking place twice, once in reality and then again in a dream (nightmare?). Fulci's trademark gore is scant and the special effects are laughable. Even die-hard Fulci fans will be disappointed.
