When sociopath Alex Gunderson kidnaps ATF Agent Jack Donovan's daughter and buries her alive, Donovan must move heaven and earth to find her. But just as Jack's team is closing in, fate intervenes in the form of a bullet and the secret to Jessie's location is lost. With only a few precious hours of oxygen to sustain her, and with not a single clue pointing in her direction, Jessie is sure to die. And Jack will trade anything in the world for just one shot to save his little girl-even his own life.
