Two San Francisco taxi drivers -- Jo (Wood Moy) and his glib nephew, Steve (Marc Hayashi) -- take to Chinatown's streets searching for Chan Hung, an intermediary who's vanished with the cash the cabbies gave him to obtain their medallion. Along the way, their odyssey leads them through a world of global politics and domestic disputes. Director Wayne Wang's quirky excursion offers insight into the cultural conflicts confronting Chinese-Americans.
