Dan, Abby, and Jordan remain traumatized by the summer they shared in the Brookline asylum. Much as they'd love to move on, many questions remain, and someone is determined to keep the terror alive, sending the teens photos of an old-timey carnival, with no note and no name. Forsaking their plan never to go back, the teens return to New Hampshire College under the guise of a weekend for prospective students, and there they realize that the carnival from the photos is not only real, it's here on campus, apparently for the first time in many years.
