Wendy Mallet, Laura Frenzer recounts a harrowing tragedy: her son, Jackson Mallet, Tom Sibley disappeared into the abandoned Abaddon Hotel more than a year ago, and a chilling video shows him racing through the halls, begging for help before his mind shatters and a shadowy cult follower closes in. The memory haunts Wendy as the hotel’s walls seem to breathe with every echo of the past, hinting that something sinister and unexplainable still lingers within.
On October 6, 2017, Suzy McCombs, Amanda K. Morales hosts a Hell House LLC special featuring Arnold Tasselman, Brian David Tracy as the charismatic, calculating host; Mitchell Cavanaugh, Vas Eli as the cautious investigator (Diane Graves' coworker from the first film), and Brock Davies, Kyle Ingleman as the stubborn, thrill-seeking companion. They debate the documentary’s truth and whether the town’s reputation—or its very souls—are at stake, while a distant online server of doom-seekers watches with growing appetite. In a tense aside, the program nods to Diane Graves, whose legacy in the original tragedy lingers in the conversation as a looming shadow over the modern inquiry. The segment is a lure in its own right, a lure that someone on the outside believes will spike their website’s popularity.
A journalism team from an online outlet watches the program, led by Jessica Fox, Jillian Geurts, who insists that with Mitchell’s help they can breach the Abaddon and uncover enough material to blow up their site. The dynamic is part skepticism, part spectacle, and all danger as the team plans a covert entry that police patrols warn against. The prospect of breaking in is tempered by warnings that the Abaddon is not merely haunted but actively dangerous, a place where past tragedies seem to echo into the present.
Outside the ruin, Mitchell confronts the reality of the hotel’s pull while Jessica and David Morris, Dustin Austen, debate the moral implications of their stunt. Molly Reynolds, Joy Shatz hesitates, unable to step inside as fear overpowers curiosity. Brock Davies, Kyle Ingleman and his cameraman slip into the dining room, where the deranged founder Andrew Tully once pulled the strings of a brutal, fanatical cult, and a chilling sense of inevitability settles over the group. A quick, eerie glimpse of a Ouija board and a ghostly figure suggests that communication with the dead is less an option and more a summons.
Inside, the team discovers that Alex Taylor, Danny Bellini from the original Hell House crew, had already ventured to the Abaddon in April 2009 and struck a deal with an unseen man. The revelation raises the stakes as the crew reunites with Molly and attempts to escape, only to find themselves abruptly trapped. Paranormal activity intensifies: the ghost of Melissa, Lauren A. Kennedy the actress who died in 2009, roams the corridors, while the lifeless, hanging forms of Brock and his cameraman drift into view, their presence turning the night into a tableau of dread. They are dragged into the dining room, where the past and present collide with suffocating inevitability.
Back on the Morning Mysteries set, Mitchell argues that the hotel lures people inside to murder them and trap their souls there, a narrative that the show’s crew amplifies with every tease. After the program ends, a crew member delivers a surprising turn: Arnold Tasselman called to apologize for missing the interview—an admission that shakes Suzy to her core, because Tasselman’s departure had just been noted on screen. The revelation sows doubt about who or what is truly orchestrating the hotel’s deadly domino effect.
When Mitchell awakens inside the hotel, he finds Jessica and Molly bound, and the ghostly figures of Mac and Alex, two of the original Hell House staff, crowding the space. Tully appears, taunting Mitchell about luring him into the place and confessing that Tasselman was actually his own alter ego all along. Diane Graves’ ghost materializes at the piano, a chilling reminder of the personal histories tangled in the Abaddon’s curse. Tully imposes a grim ultimatum: to keep the dominoes falling, Mitchell must choose one person to walk out and lure more victims inside. Molly is slain, and Mitchell, overwhelmed by guilt and fear, rises in a break of circumstances that leaves Jessica screaming for help.
In the present, Jessica sits at a police station, yet a final, haunting twist reveals that she died inside the Abaddon as well, her ghost staring straight into the camera, a final, quiet indictment of the hotel’s unnerving pull and the unfinished story of those who dared to seek the truth.
