chunk: On Christmas Eve, suburban housewife Della Myers gets into an argument with her abusive husband Kenneth. After putting her two children to bed, she drives to the mall to buy some wrapping paper and cards. At the mall, she can't find a parking space for a while and angrily leaves a note on the window of a car that is parked using up two parking spaces. She leaves the store as the mall is closing, and the parking lot is nearly deserted. She notices the note is gone from the 'offending' car. As she enters her own car, the car on which she had left the note pulls up behind her.
