Paul Conroy is not ready to die. But when he wakes up six feet underground with no idea of who put him there or why, life for the truck driver and family man instantly becomes a hellish struggle for survival. Buried with only a cell phone and a lighter, his contact with the outside world and ability to piece together clues that could help him discover his location are maddeningly limited. Poor reception, a rapidly draining battery, and a dwindling oxygen supply become his worst enemies in a tightly confined race against time; fighting panic, despair and delirium, Paul has only ninety minutes to be rescued before his worst nightmare comes true.
