Comments: I'm Louis Koo. I'm an actor.

Look at me looking off in the distance. Look at me sitting here looking at a wall. Look at me lying here in my bed snuggling up to my wife. Golly I must really love her. The scene with my wife shows that I am a family man who loves his wife so when I start killing people you will be conflicted about hating me for the complete weenie I am. Oh but wait. When I was lying there with my wife and you were looking at me did you notice that there was a little tension there. That's what a good actor I am. Of course I get up in the middle of the night, sit in a chair and stare at a wall for you. I made you think a little bit even though it had nothing to do with anything. I'm just intense. But it's not my fault. Blame the director for thinking it would be a good idea to make another movie about nothing but intense shots of me being intense. Thank you.

Do you like my sideburns? I'm kind of a weird looking guy but I've stylized it to look as if it's intentional. That's part of my overall intensity. I look the same and do the exact same thing in all my movies. I just look intense.

I'm Louis Koo. I'm an actor.

Summary: A self-styled “accident choreographer,” the Brain is a professional hitman who kills his victims by trapping them in well crafted “accidents” that look like unfortunate mishaps but are in fact perfectly staged acts of crime. Perennially plagued with guilt, he is also suspicious and morbid by nature. The recent avalanche of memories of his lost wife does not make things any easier.

After one mission accidentally goes wrong, causing the life of one of his men, the Brain is convinced that this accident has been choreographed: someone is out there plotting to terminate him and his team. He becomes increasingly paranoid, walking on the thin line between reality and delusion.

When he is accosted by a mysterious insurance agent Fong who happened to be on the scene of the “accident” as well, the Brain becomes obsessed that this man must be the mastermind behind a conspiracy to take him out. To regain his sanity and to safe his life, he must strive to kill Fong before he makes his next move.
