One Christmas Eve at Evergreen Mall follows eight intertwined stories in a Midwestern mall on the last shopping day before the holiday. A diverse cast of characters — from a lovesick mall Santa to an overeager mall cop, from a pair of brainy misfit teenagers to a team of battling actors in a production of A Christmas Carol, from a petulant first-year college student to a couple of newlyweds — navigate first meetings, second chances, and last-minute choices. One Christmas Eve wraps the joys and sorrows of the season into one festive package.
