No one knows who the Penetrator is or where he lives, expect for two men. But the police blotters of cities across the nation and even as far away as Japan contain evidence of Mark Hardin's handiwork – the death of corrupt hogs at the public table, deaths of men who killed, maimed, and caused suffering among the innocent. The Penetrator is a warrior without uniform or rank, pledged to fight anyone – on either side of the law – who seeks to destroy the American way of life. Follow the Penetrator as he travels from place to place, leaving his personal symbol of retribution, a chipped blue flint arrowhead, on the bodies of society's deadliest enemies.
