Basis for a CBS Television pilot starring Dylan Walsh.ATF Agent Jack Donovan has two ambitions: take down cult leader Alex Gunderson after years of violent mayhem, and reconnect with his daughter Jessie, who has somehow managed to slip from his life. But, none of Jack's experience as a stellar cop or an absent father has prepared him for the unthinkable way these two parts of his life are about to collide.In a desperate act of revenge, Gunderson kidnaps Jessie and buries her alive. 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—unless Jack can somehow find her. Jack would trade anything in the world for just one shot to save his little girl—even his own life.
