The demonic figure appears intimately with Magpie and later murders her husband. It is suggested that Magpie may have summoned this demon through witchcraft, and the demon targets the worst of humanity, slaughtering them. This creature's presence raises questions about whether it was invited by Magpie's desire to escape her abusive husband or if it is driven by the sins of the religious community members themselves.

The religious community, led by Magpie's father who is also the pastor, reacts with suspicion and hostility. After Magpie kills her abusive husband, she claims it was an accident, but no one believes her. The community punishes Magpie by locking her in a dark room and publicly shaming her, including binding her and forcing her to stand in the sun until death. The community's response is influenced by their strict religious beliefs and fear of witchcraft.

The story centers on Magpie's strained relationship with her father, the pastor, who tries to protect her but also enforces harsh punishments. Magpie's children, especially David, remain loyal to her. There is also a revelation of abuse within the family, as Magpie's daughter reveals that her husband had abused her, leading to emotional breakdowns. Additionally, a character named Jon frees David and reveals that the father wants David to marry Magpie, though David has feelings for someone else.

The film explores themes of religious trauma, oppressed emotions, familial dysfunction, and the nature of sin. It questions what constitutes a true sin within a devout, cult-like religious community. The horror elements intertwine with these themes, particularly through the presence of the demonic figure and the community's witch hunt against Magpie.

The small, devout religious community creates an atmosphere of oppression and fear, where accusations of witchcraft and strict adherence to religious doctrine lead to harsh punishments and social isolation. This setting intensifies the tension and conflict, as the community's collective judgment and fear drive the witch hunt against Magpie and shape the characters' actions and fates.
