The film is set in a 17th century depilated Neapolitan building where wondering ghosts supposedly dwelt. Pasquale Lojacono and his young wife Maria both moved into this building in the hopes of a nice life.
Maria is unaware that her husband Pasquale had made an agreement with the owner of the building and in order to live there rent - free, he had to dispose of the rumours that this house was invaded by ghosts. Pasquale is later influenced through a casual meeting of his wife's lover, Alfredo. He thinks that Alfredo is one of the ghosts dwelling in his home, (or forces him to believe this was an illusion, in fear of the pain of betrayal).
Alfredo starts to send gifts and money to Maria - he desired her greatly, and wished for her to live a life of luxury, the life she deserved. Pasquale the naA-ve begins to accept his presence in the house. He is grateful to his "fellow ghost" (as he sees him) without questioning anything. And Maria is finally worn out by her husband's foolishness, so successively runs off with Alfredo. But Alfredo's relatives were religiously against this scandalous adultery, so they pay a visit to Pasquale and inform him about the situation. The maddening fact is that, he still didn't want to believe that any of this was real; maybe he had fallen into denial, and wondered if they too, were ghosts themselves. When Alfredo and Maria's immoral relationship came to an end, the gifts and money sent by Alfredo slowed to a halt, and Pasquale was reduced to pure misery. His only hope was that the ghost would come back, so he could ask him for help.
Anyways, Alfredo had come back due to craziness for lack of his desired Maria (as he could not go very long without seeing her) so he returns after two strenuous months. Pasquale welcomes him as if he was his savoir, and it was at this point that Alfredo breaks down and falls to Pasquale's feet, pleading with him for Maria. During his begging session, his love for her was revealed, along with his ability to provide her with a decent life. Pasquale finally realizes what's going on. He had been a victim in saving face for a curse of public opinion. In the end, he pretends to kill Maria, in which she is convinced of her husband's good faith.
Italian law states that murders occurring on behalf of an "Honour of Love," (which consisted of a provoking leading to the murdering of a loved one) allow a person a few years discount on his sentence in prison. Once Pasquale got out of jail, he left for Scotland with his wife where he would find a job as a waiter, in a castle infested with real ghosts! The drama sinks down into the social realm, and then demonstrates a contrast between; the rich and the poor.
