Ahead of the Friday 13th premiere, Katrina said, "this season is intense, Jack and I purposefully explore locations that embody the darker side of the paranormal, as we try to understand why certain places evoke more sinister activity than others. It's exciting to see what new discoveries we can make in the paranormal field. Yet as we explore the unexplained, we can only presume to know what we're working with. At the end of the day we really don't – and that’s the scary part."

The undaunted duo will face their most fearsome cases yet, as they uncover disturbing tales from bygone pasts and unnerving paranormal activity. Jack and Katrina filter through extensive research, utilise advanced scientific equipment and enlist a network of specialists, including psychic mediums, to try and exhume answers behind these terrifying hauntings.

Jack said, "Katrina and I are breaking down walls – literally, we have unprecedented access to a number of locations and are also the first team to ever investigate some of them for TV. They're incredibly active sites for the paranormal, and we're going all in to try and capture substantial evidence."

Later in the season, Jack and Katrina will head to the site of one of the bloodiest massacres in Colonial America at Fort William Henry in New York, the 130-year-old Croke-Patterson Mansion in Colorado that's said to be plagued with paranormal activity, and the once-thriving Thomas House Hotel natural springs resort in Tennessee where guests fell victim to deadly waters.

The duo will also investigate the century-old Iron Island Museum in New York that's rumour to house two paranormal portals, the Haunted Hill House in Texas that's said to be plagued by demonic activity, and a network of underground tunnels under Portland, Oregon with a sinister history linked to slavery and kidnapping.

Perhaps the strangest location that is billed as being a part of the series is the Ohio State Reformatory in Mansfield. The episode's write up tells viewers that the "deadly prison" is best known for its role in the movie, 'The Shawshank Redemption'. Since this movie is entirely fictional, the relevance of this statement remains to be seen.
