The latest episode of the CBS TV series "Madam Secretary", "Tamerlane", aired 3/15/15, revolves around a coup plot by a rogue US cabal to effect regime change in Iran and sabotage the ongoing peace talks between the US and the Iranian administration headed by the moderate President Shiraz.  Though, initially, Kadivar, Soroush and Abdollah are also viewed as suspects, while Khorsandi, derisively referred to as the Rat of Ramin (and who knew that Ramin would have a rat?), is dismissed offhand, US officials eventually figure out that the Iranian coup leader, expected to assume power upon regime change, is none other than the western-educated equestrian expert Jafar Alinejad, whose absence from the scene led to the failure of the Green Revolution.  Jafar khan, a decorated Iran-Iraq war veteran, used to serve as Iran's UK ambassador until his falling out with the irritable Ayatollah Ruhmeini over foreign policy and nuclear ambitions, which forced him to run for his life to Canada. To assure the ever-suspicious shifty-eyed Iranians that the US government isn't behind the coup effort, the Secretary of State clandestinely travels to Iran to personally expose the coup, which is to originate from the Bandar Abbas Air Base, to the Iranian authorities, thereby restoring trust between the two governments and salvaging the peace talks.

She stays at the home of the personable Foreign Minister Zahed Javani, his charming wife, Marajel, the architect of downtown Tehran's impressive Zarand Tower, and their above-average little boys, Abdol and Katan, all of whom speak fluent English and broken Persian with a haphazard mixture of Arabic and IndoPakistani accents.  The astute viewer will no doubt surmise that, given their Punjabi features, the uncharacteristically-tall Foreign Minister and his family must be natives of Iran's Sistan and Baluchestan province.  Despite Madam Secretary's best efforts, the coup hits the fan while she's in Tehran. Tanks roll in the streets, shrapnel rip through homes and bullets tear through bodies.  Actually, there's only one short scene of violence.  Towards the end, as she's riding through what appears to be a street in the Northeast US, we immediately realize that Madam Secretary is leaving Tehran, once reflections of bodies hung in the streets roll across her car window.

At least in the US, the episode can be viewed for the next few weeks at this CBS site. Otherwise, you can read a synopsis like this one.
