An Organization of Dreams (2009)

Brief synopsis:
A writer returns, disillusioned, to London and Paris. He begins on a story: a sleeper cell of young, glamorous urban terrorists. Gabriella, glamorous trophy wife of a young king-in-exile, holed up in an opulent London riverside penthouse, falls under the spell of a modern-day Che Guevara and, Patty Hearst-style, enlists in The Cause. She is sent to Paris under the 'front' of a drama student aiming at film. She takes her studies exceptionally seriously: encounters Bernard Stiegler, the leading philosopher on the subject of cinema and the human condition, and other luminaries. And she meets fellow-"student" activists, half-sister and -brother Julia and Sam, skilled actors who seem more interested in petty crime and scams. Their father is a political prisoner held in London; is he the master-mind? Has he been grooming them since childhood?
Our writer adopts the persona of a sleuth as he follows these anti-heroes. Books are passed, stolen: do they bear coded messages? Why is Gabriella obsessed with capturing her interviews on an outdated Nagra tape-recorder? What is their connection with the incipient terrorism on the city streets?
So our writer/sleuth uncovers events; but is he documenting actuality, or inventing a fiction?
