Psychic medium Chip Coffey gave fans a little taste of what they can expect on Halloween Eve night when they tune into "Exorcism: Live!," the first-ever live broadcast of an exorcism on Destination America, People reported. In a new sneak peek, Coffey offered his explanation of what lurks in the house that inspired the terrifying 1973 film "The Exorcist."

"I hear people say 'if there is something dark at this house,'" Coffey says in the clip. "There's something dark at this house, that's not a question mark."

The house is located in the suburbs of St. Louis, where the exorcism of a 14-year-old boy named Roland Doe took place, as previously reported by HNGN. Doe's exorcism was the inspiration for William Friedkin's classic 1973 horror film "The Exorcist."

The home remains one of the most haunted buildings in America. Coffey will team up with paranormal investigative team Tennessee Wraith Chasers (of "Ghost Asylum") to perform a live séance and exorcism in the house, the first-ever to be broadcast live on television.

"Who do I think these little entities are? They're demons, they're Satan's minions, they're his worker bees, his drones," Coffey explained.

The team is gearing up for their live exorcism of the house, and fans are encouraged to follow along through an interactive live broadcast, according to a press release obtained by TV by the Numbers. Live camera feeds can be accessed through the Destination America website, where viewers can track paranormal activity and report their findings.

"What's the worst case scenario that will happen?" Coffey asked. "All hell will break loose. It's gonna be a night to remember."

Watch the full sneak peek below and be sure to catch "Exorcism: Live!" on Friday, October 30 at 9 p.m. on Destination America.
