Fifty-year-old Marcy Taggart's husband has left her for another woman. Devastating as that may be, it hardly compares to the death of her 21-year-old daughter, Devon, in a canoeing accident. Her body was never found in the icy waters of Georgian Bay, and as a result Marcy has never fully accepted her death. Now, in Ireland, Marcy yet again thinks she sees her daughter casually strolling past her on the sidewalk, which will lead to a desperate search to find the truth.
