A British schoolteacher, Gwen Mayfield, suffering from a breakdown after a traumatic experience with witch doctors in Africa, takes a job as the headmistress of a small rural school in England. Seeking a peaceful recovery, she is welcomed into the quiet village by businessman Alan Bax and his sister Stephanie. However, Gwen soon notices disturbing occurrences and a sense of unease among the villagers. Stephanie cryptically suggests something dark lurks beneath the town's surface. Unsettling incidents and a series of strange events involving the local children intensify Gwen's suspicions.

Gwen begins to uncover evidence suggesting that the village harbors an old witch cult, practicing rituals and malevolent activities. Her investigations reveal that the seemingly idyllic community is under the influence of a powerful, ancient force, manipulating residents for sinister purposes. As Gwen delves deeper, she finds herself increasingly isolated and targeted by those involved in the occult activities. Her past trauma merges with her present fears, culminating in a confrontation with the harrowing truths lying at the heart of the village's dark secrets.
