Following the death of her mother, university history professor Farran Mackenzie begins searching for her parents’ past in the Lost Villages of the St. Lawrence Seaway. Her arrival surprises the old-timers, and stirs up memories amongst the former villagers, many of whom were already rattled by the recent reappearance of Farran’s father ─ from beneath the waters of the St. Lawrence where his body had unknowingly lain since the flooding, forty years before. Then, when a friend of her parents dies in a suspicious accident soon after her arrival, Farran is forced to put her research skills to new use, before her father’s murderer finds her.
