The 'thing' that everyone is after is a biological weapon, Anthrax II, a more powerful version of anthrax. Just then, Carmen and her colleague, Philip, approach Yuen and reveal to him that they are actually CIA agents. After a long chase through the streets, Yuen finally escapes from them but shows up late for his meeting with Yong. When Yuen is at a Turkish bath, he gets accosted by a group of thugs demanding that he hands over 'the thing'. When Yuen asks her where she got her scarf, she arranges to meet him at a later date and time. While touring Istanbul, Yuen meets a mysterious Chinese woman, Yong, who has 'wait for me' embroidered on her scarf. He holds off the robbers until the police show up and the robbers flee. Shortly after leaving the bank, he encounters several robbers trying to steal his briefcase full of money. In Istanbul, Yuen uses the crucifix, which turns out to be a stamp, to retrieve the contents of Park's safety deposit box.

Yuen later realises that 'wait for me' corresponds to a phone number of a bank in Istanbul. After leaving the cemetery, Yuen and Carmen narrowly evade attacks from thugs. After Park's death, Yuen scatters his ashes at his wife's grave and finds a message ('wait for me') engraved on the tombstone. Park also gives Yuen a shiny crucifix similar to the one Yuen sees his parents holding in his dreams.

When Yuen returns to the hospital, he saves Park from a group of thugs and accepts Park's offer to play a 'game' – if Yuen wins, he gets everything Park leaves behind for his biological son if Yuen loses, he will still have fun. Later, Yuen is approached by Carmen, a reporter, who asks him questions about Park. Yuen agrees and follows Liu's associate to South Korea to meet Park in a military hospital. Later that night, a stranger called Manny Liu approaches Yuen and says that he is looking for men of Yuen's age and description on behalf of a terminally ill Korean man, Park Won-jung, who wants to pass his fortune to his long-lost son. Meanwhile, in Hong Kong, Buck Yuen, an exercise equipment salesman, inadvertently foils a bank robbery and becomes a media celebrity. Some days later, a former North Korean spy shows up at the South Korean embassy in Istanbul. A terrorist group disguised as farmers attack and kill everyone there. A news reporting team cover a story in an Anatolian village where many people have seemingly died from pneumonia while a team of scientists try to find a cure.
