In a tense, atmospheric setup, a man murderously ends his pregnant wife’s life in their penthouse atop Farhope Tower after learning she may have been unfaithful, and when he realizes the baby might survive, he calmly starts a record before hanging himself. Decades slip by, and five amateur paranormal investigators — Jake, Andre, Zoe, Judy, and Simon — chase a breakthrough in their quest for a TV series. A producer expresses interest, but only if they shoot a pilot on location inside Farhope Tower, a place infamous for its chilling history of suicides and murders. While Jake, Judy, and Simon feel the spark of opportunity, Andre harbors deep reservations: Farhope Tower is tied to a childhood brush with the supernatural, a memory he and Jake swore to leave behind. Nonetheless, Jake convinces Andre to take the chance, insisting that everything will be fine.
That night, Jake dreams of wandering through the tower as an unseen force grasps him by the neck, a nightmare that foreshadows the danger lurking within. The group arrives to an empty, dilapidated interior where a room is smeared with the message “Go Up.” Examining the place, they uncover a stack of newspaper clippings detailing the tower’s infamous incidents, including the opening murder and the surprising note that the baby survived. They reason that the top floors, where all the suicides occurred, will be the most revealing in terms of spirits and signs. A stairwell appears, and as dusk turns to night, they decide to ascend toward the tenth floor.
Jake urges the team to split up, despite Andre’s protests. [Jake] and [Simon] press ahead together and locate an office where Simon uncovers a suicide note. As the note is read aloud, Jake’s head begins to pound violently, triggering a sudden shift in his demeanor. The tension between them escalates when Simon questions whether Jake and Zoe are romantically involved, provoking a burst of anger from Jake before he snaps back to normal. The others—Zoe, Judy, and Andre—hear music and discover an unplugged radio that somehow functions. Zoe makes a fragile contact with a spirit, but the moment she asks questions, the room erupts in feral screams that shatter their equipment and cellphones.
When Jake awakens, he’s alone, bearing a gash on his head, and Simon is missing. The group reconvenes, and Zoe and Andre contemplate leaving, but Judy refuses to abandon the chance at fame, and Jake sides with her. They push deeper into the building, only to find the tower bending in impossible ways: doors vanish, staircases vanish, and the way down dissolves. Andre confronts Jake with the truth of their shared past—when they first encountered the supernatural as children, Jake was briefly possessed by a spirit that nearly killed Andre. Jake, however, refuses to walk away, and the voices drone in his head, urging him to “go up.”
In a new, terrifying turn, Zoe slips into a room that seems to defy physics—she screams, her leg snapping as she recounts that the room has no floor and she was essentially falling. She then reveals a shocking personal truth: she is pregnant with Jake’s baby. The atmosphere grows even more perilous as Simon’s missing presence returns in the form of whispers and distant clapping, and Andre is suddenly overtaken by a hostile spirit that does not merely haunt but compels him to disembowel himself. They locate Andre’s body and realize the dangers are intensifying. The trio presses on, hoping to find a way out, but Zoe is seized by a surge of possession, flailing and moaning before miscarrying the baby. She collapses afterward, inconsolable, while Jake tries to comfort her, leaving Judy horrified and retreating.
Judy discovers Simon’s GoPro on the floor and watches footage that reveals a harrowing truth: Jake murdered Simon while being controlled by a malevolent force. Jake finds Judy and becomes possessed once more, chasing her through the corridor as a ghostly presence urges him to ascend. Judy escapes and races toward the rooftop, where a spectral force seizes her and compels her to stab herself in the throat.
With the tower pushing its fearsome puzzle to its limit, Jake and Zoe reach the penthouse. Zoe uncovers a photograph from the opening scene that exposes a devastating secret: Jake is the baby who survived, and the spirits of his murdered mother and her killer have haunted him since childhood, tugging him deeper into Farhope’s dark heart. Jake, now fully possessed by the man’s spirit, brutally strikes Zoe down and then calmly retrieves a chair and a rope to imitate the parents’ deaths by hanging himself. The screen abruptly goes black, and for a breath the audience is left with Zoe’s gasp of air—miraculously alive—reframing the entire nightmare as a restless, unresolved haunting rather than an ending.
