V drugem nadaljevanju filma Paranormalno spremljamo dogodke, ki so se zgodili nekaj mesecev pred dogajanjem v prvem filmu. Katiejina sestra Kristi živi v premožni losangeleški soseski s svojim novorojenčkom Hunterjem, možem Danielom in njegovo hčerko iz prvega zakona, najstnico Ali. Srečno družinsko življenje motijo nenavadni zvoki, ki jih je slišati sredi noči, nekega dne pa Kristi in Daniel najdeta stanovanje v popolnem razsulu. Kaj se dogaja? Medtem ko je Kristi prepričana, da v hiši straši, se Daniel njenim strahovom le smeji. Toda zvoki in nasilje v hiši postajajo čedalje grozljivejši.
Daniel Rey along with his wife, Kristi; daughter, Ali; toddler son, Hunter, and their dog, move to Carlsbad, California. A few days later their residence is broken into, however, nothing appears to be missing. In order to prevent re-occurrences, they install a number of security cameras that will record everything on a DVR. After they hire a Spanish-speaking nanny to look after Hunter, she informs them that there is something wrong in their house and performs prayers, much to the chagrin of Daniel, who lets her go. He will subsequently regret this decision as more inexplicable and strange incidents occur, with Ali concluding, after a research, that their house may be possessed by a demonic entity.
