April 2017. Don McKinney purchases the rental cabin on Wagon Trail Road in East Stroudsburg. On his first visit there, the demon rouses the spirit of Abigail Wincoff, projecting her image to terrorize him. The demon pursues McKinney, whose foot slips into a hole in the wooden floor near the front door, breaking his ankle. He faints, collapsing to the floor. Later, he is found by his friend Gerry Andrews who calls an ambulance that brings him to Lehigh Valley Hospital-Pocono.

Joey Marks is in the best spirits since plotting and carrying out a murder in the Adirondacks. That is until Detective Philip Silverwood, from the Pocono Mountain Regional Police Department, and a team of local police officers show up to arrest and question Marks at his winery workplace in the Napa Valley of California. Marks gives the police the slip and goes to his bank to retrieve cash and fake ID from his safe-deposit box. He then stops off at a library, where he accesses a computer. He searches the Internet to learn about the investigation of the girl he killed in East Stroudsburg, Pennsylvania. He learns her name is Abigail Wincoff and that her body was found buried under a rental cabin. His only conclusion is that Estelle Rowland, the pesky, odd-looking waitress at the Victoria Station of The Stroud Inn, the only one who noticed him, reported him watching Abigail at the restaurant to the police.

Gillian Wincoff returns to the Poconos to visit and thank Andy Kirkman, the former Monroe County Sheriff, for his work on the case of her murdered daughter. Before leaving the Poconos, she visits the cabin on Wagon Trail Road, where Abby’s body had been found and immediately feels a strange presence there. She hears the soft singing of "Little Bunny Foo Foo," her daughter’s last favorite song to sing. When she looks up, she briefly sees the figure of a girl in the attic window. As if in a trance, Gillian can’t turn away from the red eyes of the ghostlike entity. Then Gillian cries and runs away in fear.

Detective Philip Silverwood and a team of local police officers search Joey Marks’ last known residence in California. Evidence is found that may link Marks to other murders, but nothing links him to the killing of Abigail Wincoff. The police also find newspaper articles printed from the Internet about the cold case murder of Randee Rae Devereux solved by the former Monroe County Sheriff Andy Kirkman. Suspicions arise as to who Joey Marks really is.

Meanwhile, Gillian is extending her stay in the Poconos and is determined to get to the bottom of it all. She visits with rental agent Joy Franklin and gets information on Don McKinney, the owner of the cabin. Gillian visits McKinney, who is in a hospital bed recuperating from ankle surgery and tells her to stay away from the cabin because there are demons there. After a nightmare with the demon that she can't remember, Gillian wakes up in her hotel room with a touch of the flu, feeling somehow the demon is trying to prevent her from rescuing her daughter from his grasp. She makes use of the time to conduct paranormal research over the Internet and contacts the Clean As A Whistle agency. She visits Millie Dozier, the maid the agency had sent to clean that cabin. A skeptical Dozier tells Gillian that indeed she felt the presence of a spirit at the cabin, is too terrified to return there, and wants no part in it. Instead, she refers her to Claude Bonanni, the Reverend at the Church of Saint Luke, her Catholic parish, believing he will help her. Gillian visits the church and informs Bonanni about the demon presence in the cabin. And how she worries that the immortality of her daughter’s spirit is in jeopardy. Bonanni takes her seriously, sets up a meeting with the bishop of the Diocese of Scranton. The meeting ends in favor of Bonanni conducting an exorcism to remove the demonic presence at that cabin, should he encounter it when he visits.

Living on the run, Joey Marks has died his hair blond, stolen a Jeep from the parking lot at the San Francisco International Airport, and has returned to the Poconos for revenge. And, to match his hair, he has taken on a gay persona as a cover. His angst is in overdrive as he stalks Estelle Rowland, waiting in the parking lot of Victoria Station, and following her to her home. In the dark of night, Estelle exits her car in the driveway near her trailer, and Marks grabs her from behind, intent on killing her. In the struggle, Estelle’s black horn-rimmed glasses fall from her face to the ground as she pulls the diamond-studded hair stick from the top of her head, and then stabs him in the hand with it. Weird that he is, childhood memories of being bullied surface as Marks is not used to women fighting back. He cowardly runs off. Unfortunately, Estelle can’t identify her attacker to the police because it was too dark, in addition to her being near-sighted.

Before fleeing to Canada, Joey Marks decides to visit the cabin on Wagon Trail Road to boost up his spirits. His stolen Jeep runs over a sharp object in the driveway causing a flat tire. He sees the ghost of Abigail Wincoff in the attic window. The front door of the cabin is mysteriously ajar. Marks visits the basement for nostalgia. The demon appears, terrorizing him. Marks runs up a few stairs and falls backward to the floor, breaking his neck. He dies slowly at the foot of the steps.

The following day, Gillian Wincoff arrives at the cabin waiting for Reverend Bonanni. He is running late, she enters the cabin and is terrorized by astral projections of Jimmy Wincoff, her husband’s late father; and Gail Wincoff, the ghost writer and older version of Abigail. The gruesome sight of the decaying body of Abigail is the next projection to show up just after the reverend arrives. A spiritual battle ensues between the demon and Abigail. The demon projects itself as Joey Marks to murder her all over again, attempting to bring out her feelings of revenge as the demon wants to keep her with him. The ghost of Joey Marks is able to see this because he did not cross over to the other side. He demands the demon continue attacking Abigail rousing the demon to take interest in his soul.

The spirits are transferred back to the hallway near the basement in the cabin. Gillain pleads with the demon to release Abby’s spirit and take Joey Marks instead, to a shocked Bonanni. In an act of compassion, the demon releases Abby from his possession and goes after Joey Marks. Their spirits intertwine in a battle that the demon wins, conquering him in the end. The glowing portal to heaven light beam appears and Gillian convinces Abby to go to the light, telling her that one day she and her husband will see her again.

Before Bonanni calls the police about the dead body of Joey Marks on the basement floor, he and Gillian agree to keep the supernatural events to themselves and the Catholic Church. Silverwood arrives and clears Gillian of any wrongdoing, encouraging her to return to her home in New Jersey. Oddly enough, Silverwood believes Marks just fell down the stairs accidentally.
