Judas is a retired rock star living on a secluded New York farm. Born Justin Cowzynski, he reinvented himself musically to escape a history of physical abuse by his father, Martin. Jude collects macabre objects like snuff films and antique weaponry, and he maintains emotional distance from the women in his life by assigning them state-based nicknames. He is forced into a desperate survival situation when his latest oddity purchase brings a malevolent spirit into his home.

Marybeth is Jude's current girlfriend, a former stripper originally from the American South. Nicknamed "Georgia" by Jude, she harbors her own traumatic history involving childhood assault. Despite Jude's initial emotional distance, Marybeth demonstrates profound loyalty and courage when supernatural events threaten their lives, drawing on her own resilience to protect them both.

Anna is Jude's former girlfriend, whom he called "Florida" during their time together. She struggled with bipolar disorder, experiencing severe manic and depressive episodes. Her troubled history and ultimate tragic fate form the emotional and supernatural catalyst for the haunting targeting Jude.

Craddock is the stepfather of Anna and Jessica Price. In life, he was a professional hypnotist and diviner who honed his skills during the Vietnam War. He is introduced as a malevolent ghost attached to a funeral suit, utilizing supernatural hypnosis to enact brutal revenge against Jude and anyone who attempts to help him.

Danny is Jude's personal assistant, tasked with managing the retired rock star's daily affairs and unusual purchases. Usually grounded and highly self-reliant, Danny becomes deeply unsettled by the supernatural atmosphere at the New York farm and begins experiencing terrifying auditory phenomena linked to the suit.

Jessica is Anna's sister and Craddock's stepdaughter. She actively orchestrated the sale of her stepfather's haunted suit to Jude, ensuring the curse would reach him. She holds Jude entirely responsible for Anna's tragic fate and remains fiercely defensive of her stepfather's legacy and methods.

Martin is Jude's abusive, hospice-bound father living in Louisiana. His past cruelty, particularly crushing Jude's hand in a door to thwart his musical ambitions, profoundly shaped Jude's adult life and defensive personality. He is currently incapacitated by illness and cared for by a nurse.

Bammy, whose real name is Alabama, is Marybeth's grandmother. She provides a brief sanctuary for the couple as they travel south, though she remains highly suspicious of their deteriorating physical conditions and the strange events surrounding them.

Arlene is the dedicated hospice nurse caring for Jude's estranged father in Louisiana. She diligently manages Martin's medical needs while handling the difficult family dynamics resulting from his abusive past.

Reese is Jessica's eleven-year-old daughter and Anna's niece. She lives with her mother and is caught in the crossfire of her family's dark legacy and the escalating, violent conflict involving Jude and Craddock.

Angus is one of Jude's two loyal dogs. Highly sensitive to the supernatural intrusions in the home, Angus serves as an early warning system and acts as a fiercely protective familiar against malicious spirits that enter the property.

Bon is Jude's other faithful dog. Like Angus, Bon reacts instinctively to the dangerous presence of Craddock's ghost, offering physical and spiritual protection when human defenses fail against the supernatural.

Nan is Jude's pragmatic lawyer. She helps him handle the legal and public relations fallout from the violent events surrounding his family and the chaotic occurrences linked to the supernatural haunting.

George is a car salesman from Marybeth's past who previously assaulted her. His unexpected presence on the road trip forces the couple to confront lingering, real-world traumas alongside the supernatural ones hunting them.

Ruth is Bammy's deceased twin sister who was abducted years ago. Her ghostly manifestation serves as an early piece of supernatural evidence for Marybeth, connecting her familial past to the haunting they face in the present.
