The pastoral beauty and joy of running an apple orchard in Vermont offers Moira and Stan Earthrowl a chance to heal after tragedy shattered their lives. Yet their newfound idyll is shortlived as "accidents" begin to plague the massive orchard: trees are mysteriously felled, tractor brakes fail, apples are poisoned.
A desperate Moira turns to neighbor and dairy farm owner Ruth Willmarth for help. Ruth's investigation reveals a link between the hit-and-run death of a local woman and the farm's strange events. Soon a list of possible saboteurs emerges, including a fanatical religious cult and a savvy land developer who, ironically, happens to be Ruth's ex-husband. But deadly warnings make it clear to Ruth that she is not immune to the encroaching danger -- or the relentlessness of a vengeful killer.
