Бременна жена изчезва внезапно от болницата. Бракът ѝ изглежда съвършен, но скоро екипът открива, че в изчезването ѝ е замесена нелегална организация, която помага на малтретирани жени.

Jack and the team search for a pregnant woman, Kathy Dobson, who disappeared from a hospital before being told that she has serious complications. As the detectives race against time to find Kathy, their investigation gradually reveals that Kathy's seemingly happy life actually hasn't been going very well. She is eight-and-a-half months pregnant and, under the tight control of her husband Paul, has withdrawn from her family and friends. Paul's brother Ritchie, who has been following Kathy and providing Paul with addresses she visits, lists a woman who may be affiliated with an ""underground railroad"" that helps battered women. When the team members find the woman, they learn that she has been assaulted by Paul—but she still refuses to lead them to Kathy.

Sa vie et celle de son bébé sont en danger. Interrogés, ses parents se montrent peu diserts, comme gênés. Samantha émet alors une hypothèse : et si l'enfant de Kathy n'était pas de son mari ?
