Natalie Foster marries Ethan Calloway, hoping for a happy life, but soon discovers a disturbing truth: Ethan's widowed mother, Victoria Calloway, has an unhealthy, all-consuming obsession with her son. For thirty years, Victoria has been the sole woman in Ethan's life—waking him, dressing him, even bathing him. Viewing Natalie as a homewrecker, Victoria wages a vicious psychological war to reclaim her son. When manipulation and lies fail, Victoria's jealousy spirals into violence, escalating to kidnapping and attempted murder. Torn between his wife and his controlling mother, Ethan is ultimately killed in a tragic accident during a struggle. Driven completely mad by grief, Victoria takes her own life to be with him forever. Having barely survived her mother-in-law's brutality, Natalie Foster, supported by her best friend Coco Hayes, is left to mourn. In the end, she scatters their ashes together, hoping that in another life, their extreme, destructive love can find peace.
