Carlo and Melissa stay at a seaside villa but everything changes when Melissa discovers an ancient book of demons and the ghost of a 10 year old boy that's been dead for 40 years. She becomes possessed and it's up to Carlo, with the help of Anna De Luca, a professor on demonology, to stop the ritual that will bring about the rebirth of a 400 year old demon.
