Scotland, 1950.

Matriarch of the Maxwell family, Rachel Maxwell, has many reasons to feel proud. Her two older children are happily married with prospering businesses and lives. Rachel’s only worry is her youngest child Ewan — at twenty-one, he is more naïve and sheltered than others. Ewan wanders through life carefree and without any direction. When a young woman named Gerda arrives at the Maxwell family party, she immediately catches Ewan’s eye. But Rachel can’t shake a feeling of unease — she senses a deep darkness lurking behind Gerda’s mesmerizing blue eyes. Ewan, blinded by love, marries Gerda, and their union soon sparks a terrible chain of events that threaten the entire family and community. Can Rachel save her family from Gerda’s malice before she changes their lives forever?
