Charlotte, a determined exorcist, enters a derelict factory to purge a demon, only to be betrayed by her own companions. Captured by the powerful greater demon Melkis, she is stripped of her holy relics and subjected to a cruel spell that heightens her sensitivity. Overwhelmed and helpless, Charlotte is forced to endure a series of brutal assaults by Melkis and the men who turned against her.
After losing her holy relic, Charlotte attempts to flee from Melkis but finds herself trapped inside a magical creature. Overwhelmed by aphrodisiac mucus and relentless sensory assault, the once-proud exorcist loses her will to resist and succumbs to pleasure. With her spirit broken and her body sensitized, Charlotte is claimed by Melkis to serve as a permanent sexual slave.
