Emma's having a hard time keeping it together. For eight years, she and her husband, Blake, have tried every conception technique, from holistic to high-tech - putting their marriage on edge, and draining their life savings dry. They finally got pregnant - but a few weeks ago, Emma miscarried and she's growing more and more despondent every day. When Emma discovers a suspicious text message on Blake's cell phone, her world shatters. Is Blake having an affair? SRU responds to a panicked 911 call, but what appears at first to be a violent domestic dispute turns out to be a volatile barricade situation, involving a potentially delusional wife, and a terrified "other woman." Things get even more troubling for both Emma and the SRU when the hostage reveals that she's pregnant - the worst thing she could say to Emma, and a tactical nightmare for the team. A pregnant hostage means they can't use any of their usual less-lethal techniques. As first responder on the scene, Ed must handle the negotiations - a delicate task that grows more complicated by the minute. And as Ed reaches out to a potentially betrayed wife, he's forced to face the problems in his own marriage.
