In the aftermath of the murder of a Russian diplomat and his mistress, a woman walks into bar in a rough area where Golgo 13 is visiting. When he leaves she runs after him and asks him to buy her. Suddenly some men try to kill them but Golgo dispatches them. They go back to a hotel and have sex and again more men try to kill them. A chase ensues and they escape to the sewers where she reveals that she is a CIA assassin behind the diplomat's death and that the men are chasing her and that she managed to hire Golgo 13 for free. After killing all the chasing men she pulls a gun on Golgo but he is quicker and kills her first.
