Golgo 13: The Professional
On his 62nd birthday, oil baron Leonard Dawson witnesses the public assassination of his son and heir, Robert.  From this point on, Leonard becomes obsessed with revenge on the hitman—code name: GOLGO 13.  Dawson spares nothing to enlist the CIA, FBI, and U.S. military in an unrelenting manhunt for his son's killer.  As GOLGO's survival depends on stopping Dawson himself, the hunter and the hunted chase each other in a breathless game of kill or be killed.
