Josanna is a middle aged woman living in a small town in Wyoming where she works as a Japanese chef. Josanna has a reputation for shooting a man who betrayed her, a reputation that is supported by the gun she carries in her car at all times. When Josanna begins an affair with a man who often cheats on her and often treats her badly, people wonder why she puts up with this man. This appears to go against Josanna's personality. However, people are not surprised when this man is found dead with Josanna beside him, her gun under her body.
