Just south of the Angeles National Forest and 35 miles west of Los Angeles, sits Ontario, California, a peaceful, quiet city of 150,000 people. The city might be tranquil, but there is one locally famous business that suffers under an extremely aggressive entity. The Graber Olive House - a family-run olive oil company, open since the late 1800s – is plagued by a nightmarish, non-human elemental, known as The Creeper. Several staff members have died after reporting ominous feelings of being touched or shoved in the Vat Room. Others have spoken of seeing this entity crawl across the ceiling. The Ghost Adventures team arrives to investigate what’s going on and ultimately prepares for a night of living Hell.
