We Have Always Lived in the Castle DVD

Merricat lives with her sister Constance and her deranged Uncle Julian. The trio are survivors of an arsenic poisoning, that killed everyone else in the family, five years prior. Merricat is bold and imaginative and protects the property with "spells". Despite being disliked by the townspeople, the sisters live an idyllic life, until Cousin Charles arrives. Charles offers to help around the house and enquires about the family's finances. Constance is charmed by Charles, and Merricat resents Charles' intrusion. As Charles and Merricat battle for control, tragedy threatens to strike again.
