A+ Movie.. Love how korean cinema never stops taking risks and produce those great plot twist movies.. You might need to rewatch it to understand it all.. It's like "Forgotten" and better for me (as i remember).. Some spoilers might help here: [spoiler] Why the officer asked him where you've been at 13th.. I guese he was burying her father.. Also he said at the building lets take my wife home to cover on the murder at that time [/spoiler]

I thought I knew everything and then- It's superb
