A strange Irish girl is "away" ever since she lay beside a drowned man. A teacher marries her, providing stability if not sanity, but the 1840s famines begin and the couple flee Ireland with their child Liam. They establish a homestead in a remote part of Ontario where a baby girl, Eileen, is born.

Not long after, the mother disappears and is not seen again for years until she is brought home dead. The son learns that she had been living by a lake immersed in her fantasies of the long dead lover. Eventually, Liam is left to care for his sister alone; they travel to a small port town where he realizes that Eileen has become an attractive young woman with desires of her own. She too goes "away" following a lover, but returns to Liam and his wife to live out her long and lonely life.
