When an eleven-year-old is abducted on her way to school, the FBI immediately sends agents to scour the area and embed Special Agent Ava McLane with the family. In the middle is local detective Mason Callahan, whose life is crumbling; he's related to the victim, and his confidential informant has just been murdered. Both he and Agent McLane hole up in the victim's family home. As Ava and Mason struggle to hold the family together, the two investigators find themselves drawn to each other.
