Style-guru Charlotte Oakes sells beautiful lifestyles, but her mentally ill daughter is an addict, her long marriage is dead, and she is pregnant with her ex-lover's baby. Stunned after witnessing a hit-and-run in Chicago that leaves a child dead, Charlotte thinks she sees her Prius fleeing the scene. Her troubled daughter, Libby, is the only one who could have been driving.
His partner and best friend killed in a drug bust, police officer Ed Kelly learns that forensics has found that the fatal bullet came from Ed's gun. Under internal investigation, Ed copes by filming cars at the site of the recent hit-and-run, hoping to catch the child's killer. There, he notices Charlotte's pilgrimages to the makeshift memorial, and over the weeks, the two become unlikely friends sharing intimate stories. But Charlotte won't trust him with her most vulnerable secret of all: her suspicions about her daughter's involvement in the accident.
When Ed finally learns the truth about the accident, he struggles with his beliefs and duties. If he keeps quiet, he has breached his commitment to the law. But if he does the right thing as an officer, he may send Libby to jail—and lose Charlotte.
