Widowed just two days after her unwilling marriage to a man twice her age, Marnie finds herself an outsider-spurned by the townsfolk who suspect her involvement in her husband's death. She has only two friends: the local priest and the madman known as Raver. When Marnie makes a remarkable discovery about Raver, whom she renames Raven, the two forge a deep bond. But the villagers see Raven's transformation as evidence of witchcraft.
