Sergeant Mark Quinn is a policeman who is known among his superiors as extremely persistent, unrestrained and merciless against criminals. The reason for this is to be found in his past. When he was a child he was the only one who has escaped a family massacre, and the murderers of his parents were never catched. In the meantime he was raised by a Japanese and teached in the arts of the Ninja. The tough, longstanding training pays off when he meets the killer of his father again… With all weapons and the precise and deadly techniques of the Ninja he takes revenge…他什么都安排好了；我只需要完全照着做，纵然有险，也会化险为夷！但就因为我的心中的自大和一点对天机谨慎的不满，却迟延了拿了一丁点时间。
