During a hot summer night in 1934, tragedy strikes when two local boys search for the truth behind a local legend. They stumble upon the Underground, a network of uncharted caverns just below the surface of Coal Hollow. Time holds no sway in the Underground. People no longer age and their wounds heal as if by magic. By morning, one boy is murdered, while the other never returns home. The Underground is hidden for a reason. Certain locals want to keep their lair secret, no matter the cost.Below a town struggling to survive both the Great Depression and the closing of the local coal mine, lives an immortal society built on the backs of slavery and pervasive immorality.
