War can do terrible things to the hearts and minds of even the best of men, but for U.S. Marine Lance Corporal Tyrone Banks the senseless deaths and unnecessary violence in Vietnam have beaten him down and smothered the compassion and good that was once inside of him. Grief stricken and suicidal; the extreme guilt over the awful things he's done pushes the young Marine beyond his breaking point until death feels like his only remaining option.Rather than eating a bullet, Tyrone volunteers for Tunnel Rat duty hoping to finally find release but instead of his carefully planned honorable death, what the marine finds down in the dark is a backdoor to Purgatory, a secret entrance into the afterlife where he'll get one last chance to right all the terrible wrongs that constantly haunt him. It won't be easy, though. Nothing worthwhile ever is. If Tyrone thought the things lurking in the jungle of Vietnam were bad, what's waiting for him on the dark side of Heaven is worse.Much, much worse...
