Kenji Hado, also called "the Hard," uses an M60 firearm to make ends meet as a bounty hunter in America, hoping to pay off his divorce expenses. Unfortunately, Masseria, a ruthless and ambitious mafia boss, sets his sights on Hard's family, beginning with an assault on his father-in-law, a highly regarded figure in the New York underworld. Hard's marksmanship may be uncertain when he's sober, but he becomes remarkably accurate after a few drinks!
