After a harrowing tour in Afghanistan, intelligence officer Amy Cornwall is eager to return home to her husband and their young daughter. But as soon as she steps into the house, she knows that something is terribly wrong. Her family is missing. The kidnappers leave a message: if she wants to see her husband and daughter alive again, Amy must complete a near impossible task - and she has 48 hours to do it. Alone, afraid and officially AWOL, Amy will sacrifice everything to find her family - her career, her reputation, maybe even her own life.
