I was simply overwhelmed by the fierce energy of this Iranian crime movie. The story is told from two opposite points of view: one from a detective who tries to nail a drug lord, and the other from the drug lord who tries to bribe the detective. They are both relentless and messed up in their own ways, which made it hard for me to decide which character I should take sides with. Also, some scenes(for example, prison packed with drug addicts) were so real that I often forgot this was a work of fiction. Everything I saw here was chaos : no true justice, no decent laws, no good guys. Very disturbing but a powerful piece of work.
