In a Hong Kong park, a man brushes against the arm of a girl sitting on a bench, and she slips to the ground, murdered. Immediately afterward, the man is killed also. It turns out the woman was connected with a jewel-smuggling ring, and the man was a federal agent. FBI agent Michael Scott is given the assignment and finds a way to sneak agent Carol into the smuggling gang. Carol goes to work for Pierre Milot, who works for the smugglers.
