Nine months into her pregnancy, Sarah Brady receives a phone call out of the blue from another expectant mother named "Sarah Brody." The woman informs her they have both signed up for the same gift registry, and due to their similar names gifts meant for Brady have mistakenly been sent to Brody's address. What seems to be an amusing mix-up is, in fact, a deadly trap. When Brady stops by the woman's apartment to retrieve the gifts, she is instead confronted by a knife-wielding Kate Smith. Brady instinctively fights back, and the struggle for the knife becomes a fight to the death — leaving police to determine whether the attack was an act of self-defense or murder.

One of only three people in the United States to survive an attempted fetus theft, Sarah Brady tells her incredible story for the first time in Saving Grace.
