When a lowlife at her cafeteria job tries to molest her, she's not surprised. When he takes another try and brings a friend, she's not unprepared. But the more she shakes them off, the harder they come back, until Darla's working her way up the org chart of an unsavory local business selling homemade porn cast with unwilling teenagers.
Darla just wants to be left alone, the same way her daddy wanted to be left alone. She's trying to make a normal life where no one needs to die.
But just like they wouldn't let her daddy alone, they can't seem to let Darla alone either. And just like her daddy, Darla has skills she can bring to bear on a difficult situation.
