John Doe, a man with no memory, wanders for days through the desert, on the verge of survival. When all seems lost, he spots a remote saloon in the distance: the Bitter Glass. In search of water and shelter, John steps inside… only to find himself trapped in a place that seems alive and haunted by the souls of the dead. The ghosts inhabiting the saloon are members of the gang, the Demons of the Apocalypse, and they ask John to fulfill their last wishes to finally find peace. But a deeper mystery looms: who is John Doe? And why won’t these souls let him go?
