Special Features :
Triad Kingpin Sam (Eric Tsang) has ruled the Hong Kong
Underworld for a good five years with an iron fist. To keep his
dominance on the crime world, Sam comes up with the most
brilliant plot - send some Triad spies to become police officers.
Among others, Ming (Andy Lau), a fresh 18-year-old recruit, is
sent in as a mole in the Hong Kong police department. Fearing
that Sam's power is growing by the day, Inspector Wong
(Anthony Wong) sends his top cadet, Yan (Tony Leung) as an
undercover cop to bring down Sam's Triad family.
Ten years later, Yan's ruthlessness as a gangster brings him
to the top as Sam's right-hand man. Ming's deviousness, and
with Sam's help, also rises as Hong Kong's top cop. But these two
guys soon play a deadly game of cat and mouse by trying to
snuff the other out. Things are complicated when Ming, after
being a cop for so long, wants to do good and Yan, after
chopping one too many thugs, gets confused which side he's on .
