Combining powerful interviews with documentary footage, this timely and compelling film takes a comprehensive look at the issues still confronting battered women twenty years after the beginning of the domestic violence movement. Featuring the stories of three women - one a police officer - who went through the Philadelphia family courts to ensure their safety, BREAKING THE RULE OF THUMB examines contemporary domestic violence in terms of changing historical definitions of abuse. Incorporating individual stories into a strong argument for legal reform, filmmaker Andrea Elovson exposes how domestic violence's seemingly personal gender issues are inextricably tied to flawed ideas of civil justice.
