After a long chase through the streets, Yuen finally escapes from them but shows up late for his meeting with Yong. Just then, Carmen and her colleague, Philip, approach Yuen and reveal to him that they are actually CIA agents. The "thing" that everyone is after is a biological weapon, Anthrax II, a more powerful version of anthrax. The weapon had already killed many people in Anatolia, which was chosen as a testing ground.

Yuen also learns that Zen, a crime lord, wants to buy the Anthrax II and had sent Yong to get close to Yuen to gather information.
