Mrs. Carpenter, a devoted Christian mother, hears rock and roll blaring from her daughter Nelly’s room and is alarmed by the influence of this “sinful” music.

Things escalate when Mrs. Carpenter finds Nelly engaging in behavior she believes to be sinful, convinced that her daughter is falling into corruption.

Determined to bring Nelly back to the righteous path, Mrs. Carpenter calls upon a local Reverend to help "cleanse" her daughter and save her soul.

The Reverend arrives and believes Nelly may be under the influence of a malevolent and lustful spirit, requiring extreme measures to restore her purity.

The Reverend begins a thorough "cleansing" of Nelly, believing his strict methods are necessary to cast out the evil influence and guide her back to the Lord’s ways.

As the situation spirals, Nelly finds herself trapped in an intense ordeal, with the Reverend’s extreme methods pushing the boundaries of salvation.
