Two years after Demonte Colony released, the third installment from the horror franchise is set to hit theatres. The Demonte Colony 3 glimpse begins with a voiceover telling us about a particular book which many people have taken from the library but have failed to return. Then, it is the librarian who finds the book and returns it, as per the records. Tense sequences follow and we also see a manuscript with the title Demonte Colony, written by R Raghavan. It is declared that people should be stopped from reading the book and that the librarian should be found at any cost.
