Although Tony Leung Ka-Fai is the loyal right-hand man of a crimelord in England, he ends up watching over his boss' family as well. That includes taking care of the boss' adopted daughter--who is in the middle of a love triangle--as well as falling in love with the boss' lover. As the boss gets crazier and crazier, Tony must choose between his loyalty to the boss, and his loyalty to the boss' family. Beautifully filmed, but in the end not very involving. The cast is surprisingly emotionless.
