There is a stranger outside Caroline's house. Her spectacular new beach house, built for hosting expensive parties and vacationing with the family she thought she'd have. But her husband is lying to her and everything in her life is upside down, so when the stranger, Aidan, shows up as a bartender at the same party where Caroline and her husband have a very public fight, it doesn't seem like anything out of the ordinary. As her marriage collapses around her and the lavish lifestyle she's built for herself starts to crumble, Caroline turns to Aidan for comfort... and revenge. After a brief and desperate fling that means nothing to Caroline and everything to him, Aidan's obsession with Caroline, her family, and her house grows more and more disturbing. And when Caroline's husband goes missing, her life descends into a nightmare that leaves her accused of her own husband's murder.
