In a rural area of California sits a building atop a hill that resembles a castle. The Preston School of Industry was a proposed as a reform school and was used to house wards, or minors under the guardianship of the state.

Today the building is a historic landmark and according to historians, volunteers and paranormal investigators, some of the spirits of the boys who were housed there, and a few employees, are still roaming the halls. Investigator Connie Brenner and administrator Sybil Griffith share some of their paranormal experiences in the historic landmark.
