In the winter of 1977, there came upon the town of Murray, Ohio a grisly event. For years it would go on to become one of the most baffling and heartbreaking cold cases in Ohio's history. In one night, seven people were gruesomely murdered inside their own homes by an unknown entity that no one has ever been able to identify. But as with most tragedies, this particular incident not only affected those whose lives were taken, but also the ones that surrounded the entire case.
At times, it takes one individual to transform the lives around them, for the better or worse. In Isaac Mercer's case, a man just recently released from a short stay at a mental institution, the better is all he can pray for.
But when strange blackout episodes and abnormal behavior resurfaces, the worst only becomes his most terrifying nightmare come true. His beloved, small family is suddenly put back into harm's way once more, and Isaac is forced to face the harrowing fact that evil has never left him...it has only been waiting. What does a man do when no one will believe him?
