Back From Hell: Six ex-classmates decide to spend some holidays together. To enjoy a short rest period and some amusement, they rent a manor house in the countryside, where to forget the raving madness of the city life. After got to know the priest living in the adjoining church, the group installs in the house. Very soon, the convivial mood goes progressively deteriorating, while in the house start to happen strange phenomena, apparently paranormal. The journey turns into a nightmare when Giorgio, one of the mates, starts to have aberrant behaviors, until he shows evident signs of what properly seems a diabolic possession. While Alessandro, his best friend, tries to find a scientific and rational explanation to the happenings, the other friends trust in Father Elia, the priest. He feels Giorgio is surely possessed by the devil, and tries to exorcise him. But in the end, all the people will figure out that what is happening goes over their ability to understand, and moreover, their possibility to control.
