Promised Land (1996) : 1x12

The Greenes are on their way to Cheyenne, Colorado when they stop to help a woman, Ellen Boller whose car has broken down on the road. Hattie becomes concerned when she notices bruises on the woman's young daughter, Sarah. Russell and Claire confront the mother and learn that she's running away from an abusive husband -- who happens to be the town sheriff (Sheriff Boller). While returning the girl's doll, Russell witnesses the abuse through the window, breaks into their house and rescues the woman and her daughter. Sheriff Boller keeps the Greenes under house arrest in their trailer until Russell returns his wife and daughter. Meanwhile, Ellen arranges for her sister-in-law Pauline to get proof of the abuse in the form of a videotape in order to prosecute. Along the way, we learn that Sheriff Boller has a long history of fear and intimidation to his credit. Boller intercepts a note and foils their plans.
