Golgo 13: The Professional (1983)

Golgo 13: The Professional, known as simply Golgo 13 (ゴルゴ13) in Japan, is a Japanese animated film adaptation of the Golgo 13 manga series released on May 28, 1983 by Tokyo Movie Shinsha. It is the first animated film to be based on the manga and the third film overall.

Plot
Professional contract killer Duke Togo—codenamed "Golgo 13"—is hired to assassinate Robert Dawson, the son of oil baron Leonard Dawson and the heir of Dawson Enterprises, and succeeds. Later, after accomplishing a hit on a powerful crime boss in Sicily, Golgo is suddenly attacked by the U.S. military and discovers that his informant has been killed by Snake, a genetically altered assassin. Aided by The Pentagon, the FBI, and the CIA, Dawson has become determined to kill Golgo and avenge his son's death.

A military force, led by Lieutenant Bob Bragan, attempts to ambush Golgo while he is in the middle of an assignment in San Francisco, California to assassinate an ex-Nazi official. The plan fails, and Bragan's entire force is wiped out. However, a dying Bragan manages to wound Golgo. Meanwhile, Rita, the mechanic that supplied Golgo with his getaway car, is murdered by Snake.

Having been consumed by revenge, Dawson begins to allow the rest of his family to be harmed. For Snake's cooperation, he allows him to rape Laura, Robert's widow, and sends his granddaughter and butler to an airport to murder Golgo with a firearm concealed in a doll. The shot misses, and the butler reaches for his handgun. Golgo shoots the butler in the chest, a crowd gathers, and Golgo walks away nonchalantly.

Dawson, in a meeting with the FBI, the CIA and The Pentagon, demands the release of Gold and Silver, two notorious murderers who were part of a covert government operation to test the survival rate of mercenaries in the jungles of South America. When the group refuses his request because Gold and Silver are on death row, Dawson threatens to halt all operations that his company controls, which include oil refineries and banks. The group agrees to his demands in fear that the economy of the country will collapse. When Laura demands to know why Dawson has refused to seek vengeance on whoever ordered the hit on Robert, he refuses to answer.

Pablo, an informant for Golgo, informs him that Dawson ordered the hit on him and that he's currently in Dawson's tower awaiting his advance. Pablo goes on to inform Golgo that his wife and children are being kept at ransom in the tower. Pablo attempts to shoot Golgo, but is killed by Golgo first.

Golgo arrives at Dawson Tower in New York City, and begins his ascent to the top floor on foot. He first plays a game of cat and mouse with a fleet of helicopter gunships sent to kill him. While on the move, Golgo is attacked by Snake, and a brutal fight occurs between the two in an elevator. An attack helicopter shoots the elevator, killing Snake while Golgo hides by the edge unseen by the helicopter. Gold and Silver are then sent to ambush Golgo. During the attack, Golgo counters both of them; bludgeoning Gold on the head repeatedly with the butt of his revolver and shooting him. Silver, blinded by rage at his partner's death, runs towards Golgo, who quickly stuffs a grenade in Silver's mouth, killing him. Golgo then proceeds towards Dawson.

Admitting failure, Dawson orders all action against Golgo to end. Golgo finally encounters Dawson at the top of his building. Following a brief monologue, Dawson attempts suicide by leaping out of the window. As he falls, Dawson remembers Robert's suicide note, which reveals that, despite receiving much care from his father throughout his lifetime, Robert was overcome with grief over the possibility that he would never fulfil his father's ambitions; unable to commit suicide, he requested Golgo to kill him. Before Dawson hits the ground, Golgo shoots him in the head. Dawson falls headfirst, crushing his skull and any evidence that he was shot. His death is ruled as accidental by the authorites.

Afterwards, Golgo encounters Laura, who has since become a prostitute. Upon recognizing him, she attempts to shoot him, but her shot misses, and Golgo casually walks away.

Production
Golgo 13: The Professional incorporated CGI animation, which was in its infancy at the time. This is most notable in a scene where army helicopters circle around Dawson Tower and attack Golgo as he climbs toward Dawson's office on the top floor.
