Family Sins(2005)

Based on the true story of the Burt family who seemed normal, upstanding members of the community but were actually deeply embedded in crime. The matriarch took in foster children who were subsequently molested and abused by her husband and children and she kept a woman enslaved and imprisoned in the basement for over twenty years until the woman's daughter managed to get to Rhode Island Attorney General David Morwitz and expose the horrors taking place in the Burt household.
