A young woman named Christine breaks into a convent and kills every nun she comes across before setting fire to the place and leaving. The convent becomes an abandoned building and, years later, is a popular place for college students to break in and vandalize, as it is reported to be haunted. It is particularly popular for sororities and fraternities to break in and try to spray-paint their letters on the bell tower. One night, a young woman named Clorissa goes there with her friends. She is joined by her old goth friend Mo, her nerdy brother Brant, ex-fraternity brother Frijole, the cheerleader Kaitlin and her dog, and fraternity brothers Chad and Biff.
At the convent, Biff and Frijole start bullying Brant under the pretense that it is just routine hazing that all must go through to join the fraternity. The group begins to explore the convent but are stopped by the arrival of two police officers that force them to leave and take a cannabis joint that one of them had been holding. Scared to lose her scholarship if she is caught by the police, Mo decides to stay and hide in the convent, having persuaded Frijole to cover for her by promising him they would have sex. The group then goes to a diner, where Frijole says that they must return for Mo and a large stash of pot that he left in the convent.
In the convent, Mo is grabbed by a group of gothic Satanists who want to sacrifice her as part of a ritual to give its leader Saul power and summon Satan to Earth. While listening to the group talk to one another, Mo realizes that they have no idea what they are doing. She tries to talk them out of killing her, to no avail. After being stabbed in the heart, Mo is possessed by one of the demons that were already inhabiting the convent and begins slaying everyone in the group except Saul and Dickie-Boy, who manage to escape. The others return to the convent and are also murdered one by one, until only Clorissa and Brant remain. Saul kidnaps Brant to sacrifice him to Satan and send the demons back, but Brant escapes and Saul is killed and converted by the demons. Brant does not get far, as he and Dickie-Boy are taken by the demons to use them in a sacrifice.
Clorissa flees to the nearby house of a now-grown Christine, who reveals the full story of the convent, which also served as an orphanage and home for pregnant teens. Christine attacked the nuns and the priest running the place because they had become possessed by demons and intended to take her baby and use him to create the Anti-Christ. She saved her son, but had to spend years in a mental institution as a result. Every few years, college students break into the convent and become possessed by demons, but little comes of it because she fought them off and because none of them were virgins (meaning that Mo's claims of virginity were false), as only a virgin can become the Anti-Christ. Upon hearing that Brant is a virgin, Christine and Clorissa return to the convent. They fight off most of the demons but cannot stop them from killing Dickie-Boy (who was also a virgin), who becomes the Anti-Christ. Christine then urges Clorissa and Brant to flee, as she will blow up the convent with herself and the Anti-Christ inside. Clorissa and Brant escape the convent and find that the only other survivor is Kaitlin's dog, which Clorissa takes home with her. At home, Clorissa lies down on her bed before being attacked by the dog, as it was also possessed by a demon.
