I wonder if this was a pioneer sister!
Here's the blurb
After drug dealers rape and leave her for dead in the woods, beautiful door-to-door religious-tract peddler Catherine (Cheryl Lyone) trades in her prayers for a pump-action 12-gauge and sets out for payback against the men who attacked her. But once she gets a taste of holy vengeance, Catherine's thirst for blood becomes insatiable. This over-the-top exploitation flick from director Joseph Guzman contains graphic images of sex and violence.
