1982. A group of drug couriers shoot a border patrol while illegally crossing the border between Mexico and the United States. American intelligence officers discover at the scene of the tragedy shell casings from the Scorpion, a submachine gun used by the Kurds during a secret CIA operation in northern Iran to destroy Kurdish rebels. Then several secret agents disappeared without a trace, and now, exactly seven years later, an investigation into an incident on the US-Mexico border leads to the trail of one of them. Meanwhile, the CIA receives information that a well-known Kurdish terrorist has entered US territory and the purpose of his visit is revenge on the former US Secretary of State.
