As movies struggle to stay alive and relevant, Matt and his core team of infighting executives battle their own insecurities as they wrangle narcissistic artists and craven corporate overlords in the ever-elusive pursuit of making great films. With their power suits masking their never-ending sense of panic, every party, set visit, casting decision, marketing meeting, and award show presents them with an opportunity for glittering success or career-ending catastrophe.
