"So much of what Brit and I have to do as writers is to go live,” says Batmanglij, who actually stayed in an anarchist collective with Marling prior to making the film— understanding the importance of “living something authentic” in order to come back and tell an original story. Starring Ellen Page, Alexander Skarsgard, Patricia Clarkson, and Marling, the film goes as follows:
Someone is attacking big corporate CEOs and forcing them to consume harmful products they manufacture. An elite private intelligence firm is called into action and contracts ex-FBI agent Sarah Moss to infiltrate a mysterious anarchist collective, The East, suspected to be responsible. Skilled, focused, and bent on success, Sarah goes undercover and dedicates herself to taking down the organization. She soon finds, however, that the closer she gets to the action, the more she sympathizes with the group’s charismatic leaders.
