Paul Conroy is not ready to die. But when he wakes up 6 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 90 minutes to be rescued before his worst nightmare comes true.
