Last year Wilson Yip achieved success with his movie, 'Bio-Zombie'. This year, he directs a police action thriller bringing his unigue style to the heroic bloodshed sub-genre of Hong Kong cinema.

The casting is quite strong, featuring Francis Ng and Louis Koo as the 2 cop buddies. While on an undercover assignment, they live in an apartment with Helena Law. Ms. Law is brilliant as the slightly off-center granny. During this time, the boys also have love affairs that confuse, then strengthen their friendship.
