The film is set at John R. Rogers High School in Spokane, Washington. Ten years prior, student Abel Frye, a victim of bullying, had committed suicide by hanging himself on the school property. Fast-forward to the current day, when several student football players are mysteriously becoming gravely ill. Just before falling into a coma, each victim is heard screaming the spirit's name, Abel Frye. In an effort to get to the bottom of the haunting, the school turns for help to the Veritas Project, a team of highly trained investigators who work undercover to unravel the truth about paranormal activities. The Veritas Project consists of the members of the Springfield family, including father Nate, mother Sarah, daughter Elisha, and son Elijah. The high-school students in the film represent various social classes or youth subcultures, including jocks, geeks, and goths. Prominent among the students in the film are members of the goth culture, who worship the ghost of Abel Frye. The goth students are led by Ian Snyder. Unbeknownst to the rest of the school, Norman Bloom, a young geek Elisha befriended, is Frye's nephew. In retaliation for the bullying and mistreatment inflicted on the different students, Bloom exacts revenge on the popular football players. Bloom's plan includes gaining access to the locker of each targeted bully and placing a deadly male spider, trapped in a straw, inside the locker. Bloom then gives the bully tainted money, upon which he has secretly placed trace amounts of female spider pheromones. When the unsuspecting bully reaches into his locker, the waiting male spider is easily attracted to the pheromones, and then crawls out and bites the student. Among the effects of the toxin, the affected students experience hallucinations, believing that the ghost of Abel Frye is after them. At one point, Bloom accidentally puts an additional female spider in one of the straws, which results in thousands of deadly spiders overtaking the school. Elisha Springfield, attending the school undercover as a student, eventually figures out the mystery and the diabolical plot designed by Norman Bloom. In fear of being discovered, Bloom attempts to keep his involvement in the haunting hidden by poisoning both himself and Elisha with a spider, hoping that they will both die. When Elijah figures out that Bloom is behind the sinister attacks in the school, he races to find his sister and the Springfield family rush to professor and scientist Dr. Algernon Wheeling, who saves Elisha with an antivenom. In the end, the students at Rogers High School are protected not only from haunting and harm from others, but from the harm brought on by their own hatred and fear, as well.
