Mary Harrington doesn't want to revive her past. She certainly doesn't want her son and granddaughter to know what she did forty-four years ago. But when two teenagers from a local gang try to mug her, old habits are hard to forget. Sergeant Jack Rossini, Rivershore, Michigan's lone investigative detective, initially doesn't believe an 'old' woman could have put the youths in the hospital, but once he meets Mary, he becomes curious. That curiosity grows when he discovers there's no record of her existence prior to forty-four years ago. Mary and Jack's lives continue to intersect as the gang vows to teach Mary a lesson, and a man from Mary's past arrives in Rivershore, threatening to reveal her secrets.
