After a two-year layoff, Jackie Chan returns to Hong Kong film with this international-flavored action-adventure from director Teddy Chan (Downtown Torpedoes). Chan is Buck Yuen, a fitness equipment salesman who happens into an international spy chase. Buck is fingered by a dying Korean spy as his long-lost son, and sets out across the globe to find his supposed inheritance.
Buck's journey leads to to Turkey, but things aren't what they seem. Even though he finds the money, numerous parties begin chasing him asking about some other package that he isn't entirely aware of. Among these parties is evil businessman Wu Xing-Guo and his innocent moll (Vivian Hsu). The missing package turns out to be a deadly virus called Anthrax II, and everyone and their brother wants it for the obvious biological warfare applications. What's a normal guy like Buck to do?
