Somewhere in America, a political assassination is being planned. The target is an Arab leader with a very big moustache. The participants are a hand-picked trio lead by a fatherly, once-liberal colonel. There is an uptight communications expert keen on following orders and a full-of-himself sniper.
There is a final member of the party, Jessica Stein, a sharply intelligent and successful explosives expert who has become a thorn in the military's side since she made a complaint about harassment and was splashed all over the front of the New York Times. Still, this woman is a professional ("success is my feminism") and she'll get the job done.
The Riot Group has been cutting a swathe through Edinburgh in recent years with its portraits of an America in crisis, and it hits the bull's-eye with this stylish and intelligent reflection on the moral conundrums that open up when you start trying to play policeman to the entire world. A real piece of tense, hard theatre about the tense, hard realities of the times we live through.
