 Sarah Bailey, a sixteen year old troubled teenager with a painful past and a history of suicidal tendencies and hallucinations, moves to L.A. with her father and stepmother to start a new life - and is enrolled into a Catholic school. It is at school that she comes into contact with three unlikely friends, Nancy, Bonnie and Rochelle, all who are socially outcast with various problems in their lives that they wish they could fix. Nancy, Bonnie and Rochelle dabble in occult practices, and when they notice Sarah has the powers of a natural witch, they talk her into joining their coven. When Sarah joins, they soon realize that with a fourth witch in the coven they can begin to cast spells they couldn t before, and begin to amend all the things wrong in their lives - but like everything else in life - things come with a price.
