Things that seem too good to be true usually are. That's what Chris Jackson and his wife, Heather, discover when they buy a house on the shores of Lake October for a fraction of its market value. Although meant to be a year-round idyll where they can raise their two sons without the encroaching dangers of the inner city, the house becomes more prison than sanctuary when the Jacksons begin hearing stories about a presence known only as The Lady that is said to inhabit Lake October.
Those stories take on new meaning when strange things start to happen around the Jackson household. Chris and Heather walk in their sleep after hearing a gentle song on the night air. The children, barely old enough to speak English, speak in foreign tongues during fits of incoherency. Even the family dog goes berserk, nearly killing the youngest son, Nicky, in a fit of uncharacteristic rage.
