A young seminary student named Khoma Brut is traveling home for a vacation with two of his fellow students. They get lost and seek shelter at a remote farmhouse. The old woman who owns the house gives them each a place to sleep, but that night, she reveals herself to be a witch. She attacks Khoma, but he manages to fend her off, severely injuring her in the process. Terrified and confused, Khoma flees back to the seminary. He is soon summoned by the wealthy father of a young woman who is dying under mysterious circumstances. On her deathbed, she specifically requests that Khoma reads her last rites.

Khoma reluctantly agrees and travels to the father's estate, only to discover that the dying woman is the witch he had fought off earlier. Despite his fear, he is forced to stay in a church by her coffin for three nights to fulfill her last request. Each night, supernatural horrors intensify as Khoma struggles to survive against dark forces summoned by the witch's spirit. He battles ghouls, demons, and other malevolent entities that seek to torment him. The tension and terror escalate each night, testing Khoma's faith and resilience against an ever-growing tide of sinister magic.
