Driven by an obsessive, morbid curiosity about the afterlife, ambitious
medical student Nelson Wright convinces his brilliant peers to participate in a dangerous, unauthorized experiment: clinically dying and being resuscitated. Meeting in secret at an abandoned hospital, Nelson is the first to undergo the procedure, hooked up to a battery of sophisticated monitoring equipment while his colleagues—David, Rachel, Joe, and Randy—stop his heart for a terrifying minute before bringing him back. Revived, Nelson experiences vivid, euphoric flashbacks of childhood grief, which miraculously cures his severe insomnia and sharpens his cognitive faculties. Intrigued by his success and eager for their own breakthroughs, the rest of the group eagerly demands their turns in the chair, each harboring deep-seated psychological scars and buried regrets they hope to resolve. Rachel relives a repressed, traumatic memory of her father’s suicide. David confronts the guilt of sabotaging a childhood rival’s academic career. Joe records explicit home videos that capture his reckless, hyper-sexualized anxieties, while Randy grapples with the immense pressure of living up to familial expectations. However, their scientific hubris soon exacts a terrifying toll. The boundary between the living world and the great beyond begins to dissolve, and the clinical experiments unleash supernatural consequences. Each student starts experiencing increasingly violent, corporeal hallucinations that mirror their deepest guilts and shameful past mistakes. These malevolent apparitions inflict actual physical harm, escalating from
psychological terror to brutal, life-threatening assaults in the waking world. Nelson’s phantom tormentor turns out to be a boy he bullied and accidentally caused to die in his youth, a manifestation demanding retribution. As the physical and mental health of the group rapidly deteriorates, they realize that crossing the threshold of death has invited judgment, and the afterlife refuses to let them go without settling accounts. Desperate to break the curse, the friends must confront their individual moral failings and seek genuine atonement for the sins of their pasts. They discover that survival depends not on scientific mastery over mortality, but on human forgiveness, guilt-cleansing, and taking responsibility for the choices that haunt them. In a chaotic climax of terror and redemption, they fight to lift the spectral curse before their hearts stop permanently, ultimately learning that some doors, once opened, threaten to consume the living soul entirely.
