 Best friends Karen Wright and Martha Dobie are headmistresses at a successful private school for girls in New England. Mary Tilford, a spiteful, angry child, is caught in a lie and punished. In retaliation she tells her grandmother, a matriarch in the town, that Martha was "jealous" of Karen s relationship with Dr. Joe Cardin, and tells that Martha s Aunt Lily thought those feelings were "unnatural." Grandma believes her and pulls Mary out of school. The word quickly spreads and within days Karen and Martha are faced with empty classrooms. Joe is fired from the hospital for siding with the teachers. Karen and Martha sue for slander in a case that makes national headlines.
