There is no heaven. There is no hell. Instead, when you die, you must enter a full-blown survival game in which you must survive the same number of days equal to years lived on Earth (For example, if you died at the age of 85, you must survive for 85 days in the game). If you manage to stay alive for your total number of days, you are allowed to return to Earth as a baby. If you die, you face eternal punishment in a lake of fire. However, when nineteen-year-old Nathan Glyder enters the game, he just might change it forever.
