When a surrogate grows too fond of the baby she carried for a young couple, they try to disengage from her. But the surrogate starts poisoning the mother (with no danger to the child) in a scam that will keep the surrogate around, and then, when mom is gone, the surrogate will get the child, the husband and the suburban life she so earnestly covets.
When a couple hires their surrogate to nanny, their bond grows tight, making the sister-in-law increasingly jealous. Soon a web of distrust, lies and mystery entangles the three women, resulting in danger and near death when one of them crosses the lines to get the child, the husband and the suburban life she always coveted.
