And if her husband's life is in danger, then so is hers and their baby's.

As memories of her happy life with Jake morph into haunting flashbacks, Mallory realizes there's a dark side to their relationship and that their marriage is far from perfect. She wonders if she knew her husband at all.

Now she must decide whether it's worth having him home or if she should forget he ever existed. Mallory has so much to lose-the perfect little family that she's always imagined.
