The sleepy town of Hallow's End takes its name-sake holiday very seriously, and this Halloween promises to be the most serious yet. With conflicting personalities and jealous rivalries, a group of college students are preparing for their annual haunted house event when an eerie jack-o'-lantern and mysterious old book arrive at their doorstep. All hell breaks loose when someone reads from the book and the innocent terrors of the fraternity's haunted house transforms them into deadly reality. Trapped inside the haunted house, students are murdered one by one, only to come back as the creatures whose costumes they were wearing. By evening's end. a handful of survivors must take one last stand against a houseful of ghouls, ghosts, zombies and vampires.
