The building was non-descript, really. A cement block bunker in the middle of a fenced-in field; a dead end location in every sense of the word. You wouldn’t know by looking at it what horrors its walls had seen; there no one was left to remember.
Line after line, they were ushered in, told they were to be decontaminated. Only a few discerned there was no exit, no plan for them to leave. That realization dropped some to their knees in prayer, knowing their time was short.
The only testament left of this nightmare was the single tap on the wall. Powerless now, it controlled all then. Life, death, on, off. All in a single turn of the screw.
