When Katherine finds out that her father's company is about to close the paper mill they own in her rural-Pennsylvania hometown, she comes up with a plan to save it. Going back to get the city council's approval, she runs into someone from her past: Jane. In high school years ago, Katherine dated Jane's twin brother Sean, who committed suicide after Katherine ended their relationship. Although his death wasn't Katherine's fault, Jane hasn't been able to forgive her, blaming nearly every life issue she and her mother have been forced to face since the family tragedy on her, and now she decides to finally get revenge on the woman whom she believes ruined her life.
