If the road to hell is paved with good intentions, then the billboards leading to that fiery abyss are littered with the words, thoughts and deeds of our self-righteous indignation.

After being murdered by a corrupt police officer, Detective Mason White opens his eyes and discovers he is not in Heaven or Hell, but very much alive in Purgatory. He is stranded in a barren wasteland, trapped with millions of other souls who are awaiting final judgement. Fate has something special planned for Mason as the archangel Michael appears, and gives him a mystical map to the world of Purgatory.

The map is a divine key to leave the barren land and also very powerful for those who carry it. The dark entities who roam Purgatory to claim lost souls also have a desire for the map. When word gets out that the map is with a human soul, every creature in the dark realms of Purgatory want to get their claws on it.

If Mason wishes to get out of the wasteland and ascend to Heaven, he must take the map, find the human souls whose names are written on it, and lead them out of Purgatory, in the hopes of saving his own soul.
