Introducing Mark Hardin, "The Penetrator," at war against the L.A. heroin trade. Mark Hardin... He'd learned how in Vietnam: Infiltrate the enemy's position, determine the plan of action and then strike swiftly, taking out as many key men as possible, wreaking destruction, leaving chaos in your wake. He is a new breed of warrior, without uniform, without rank - dedicated to the American way of life, and pledged to fight anyone who seeks to destroy it. On either side of the law. That's why he's in Los Angeles. Just the beginning of a long and lonely series of brush fire wars.
