In a small Kansas town, Betty (Renée Zellweger), a kind and considerate diner waitress, is a fan of the soap opera A Reason to Love. She has no idea that her husband, Del (Aaron Eckhart), a car salesman, is having an affair with his secretary and that he intends to leave Betty to pursue a relationship with her. She also doesn't know that her husband supplements his income by selling drugs out of the car dealership. When Betty calls to leave a message about borrowing a Buick LeSabre for her birthday, her husband tells her to take a different car, as the LeSabre (unknown to Betty) has stolen drugs hidden in the trunk.
