Upper East Side stay at home mother, Reilly Peterson, stumbles onto a terrorist plot while playing with her gregarious children in Central Park. Because she is obsessed with political correctness, she is hesitant to call the authorities and pursues the could-be terrorists on her own. As she becomes more certain of the plot, she drags in an overweight old boyfriend, her stylish investment banker husband, a new preppy mom friend and her politically incorrect best friend, Jenn. Together, they shop, interpret Farsi, discuss Middle Eastern affairs and ruthlessly bash Republicans. While the ad hoc group attempts to save the free world, the unlikely group of terrorists, including a loud Southern evangelist and a quiet Iranian chemistry professor, deceive each other and an unexpected twist leads millions to question the Christian bible.
