Donald Kohler lives under the crushing weight of childhood trauma, bearing physical and psychological scars inflicted by his abusive parent. When her sudden passing grants him a terrifying freedom, the long-repressed voices in his mind seize total control. He constructs a soundproof, steel-plated chamber upstairs, transitioning from a reclusive laborer into a calculating predator. Driven by a twisted compulsion to replicate his own torment, he traps unsuspecting women, strips them of their autonomy, and incinerates them. As his grip on reality fractures, his coworker Bobby Tuttle and a local priest, Father Gerritty, grow increasingly alarmed by his erratic behavior. Their desperate intervention triggers a chaotic, fiery reckoning inside the crumbling family mansion.
