An apocalyptic phenomenon called The Event has wiped out most of the human race, leaving a screaming sand tempest in its wake. The only area of the planet that remains unaffected is a circular plot of land containing a special house.

Ten survivors live in this house, all of which have had their memories wiped clean of their past. Most of them have mutated into unspeakable monsters, all except an unnamed protagonist, the only normal human survivor in the house. Recently, he discovered a picture of a beautiful young woman who may be a key to his past, as well as the cause of The Event.

The unnamed man’s friends, Francis and Christine, have also found artifacts to unlock the mysteries of their fates. But how long will it be before the seven other mutated tenants cause this man’s demise?
