Golgo 13

A man hires Golgo 13 to kill Carronte, a terrorist in a maximum security prison, to avenge the death of his family in a random act of terrorism. However Carronte's cell is behind a revolving door and sliding door and only has a small aperture window. Golgo 13 has to maintain his posture for ten hours in order to make the shot. Knowing this is impossible he contacts a man who was involved in an athletic doping scandal who can make a drug to relax his muscles. Golgo manages to shoot the target but his muscles are in a bad shape and requires professional massage to recover. The chemist had offered to do this but took Golgo's vital statistics to an FSB contact who would give him a huge reward for killing Golgo 13. As Golgo can hardly move he moves to kill him but does not anticipate how well prepared the professional is.
