A chance encounter with a stranger in a cemetery, and an agreement to assist in what seemed to be a simple genealogical query, soon turns into two questions: "Who Was Erin?" and "Who murdered Aaron?" over twelve years ago. Never one to let a good mystery pass her by, Shell, with the aid of husband, Joe, sets out to find answers. This cold case file eventually leads Shell and her newly acquired entourage to Ireland and back. They soon feel they know the answer, but can they prove it?
