On Large Mouth Lake - S1.E42

Duke kills two moose with one shot whilst hunting in Canada with a custom powerful rifle and is arrested by two park rangers for going over the allowed quota. Whilst in custody at the ranger station some thugs try to kill him but he shoots them first and escapes kidnapping the female thug. It is revealed that the CIA have hired Duke to kill McCord a double agent before he can defect and the woman he kidnapped works for McCord. Golgo burns her clothes so she cannot escape the log cabin as she would freeze to death outside and gives a local girl an expensive coat to look after her. The woman promptly escapes, stealing her clothes, and meets up with McCord to take him to a helicopter to escape. As they travel on a snowmobile she realizes too late that the escape was too easy and that against the white backdrop, the red coat she stole sticks out and that Golgo 13 has a rifle powerful enough to shoot through multiple targets. Using the red coat as a target, Golgo kills both the woman and McCord.
