When night falls on Hong Kong the fate of the many is decided by the few, as the gang leaders and their people scramble to make a stand. Personal vendettas collide with old fashioned honor and modern practicalities, and the reign of the city will fall to whoevers left standing in the end...
Jiang Hu arrives at a time when the Hong Kong movie industry still appears fresh and invigorated in the wake of the successful Infernal Affairs trilogy. It tackles a good old fashioned genre, the triads movies, with new-found gusto, and it stars a host of respected Hong Kong actors.
I just got done watching Jiang Hu and really liked it. Read this review which I agree with exactly.
