On the morning of their fifth wedding anniversary, Amy Dunne disappears from their Missouri home--and her husband, Nick, looks like the reason.
Nick scrambles to find a suitable alibi, desperately redirecting the investigation towards any suspect but himself. Meanwhile, Amy's diary entries reveal a portrait of a marriage gone sour. Gracious wife, beloved only child, the inspiration for an award-winning book series--it is unthinkable that anyone could wish harm on such a lovely woman.
But Nick has harbored resentment against his bride for years, envious of her inherited wealth, exasperated by her city-girl lifestyle. As his excuses run thin and his secrets come to light, all the signs point to his guilt.
But no one can answer the question: what happened to Amy?
