Colonel Naderi and Colonel Nasrollahi are two veteran police officers in charge of the Drug Enforcement Agency. They are trying to solve a major drug case revolving around a stash of 60 kilos of crystal-meth hidden somewhere by the famous drug kingpin, Majid Bastan, but all their efforts so far have been to no avail. In the meantime, Colonel Naderi starts receiving reports about extortion, coercion and blackmail by none other than his old friend, Colonel Nasrollahi. Little by little, clues start popping up, connecting these two seemingly unrelated matters.
