A group of Egyptian revolutionaries battle leaders and regimes, risking their lives to build a new society. The Egyptian Revolution has been an ongoing rollercoaster over the past two and a half years. Through the news, we only get a glimpse of the bloodiest battle, an election, or a million man march. At the beginning of July 2013, we witnessed the second president deposed within the space of three years.

Directed by Jehane Noujaim, the film was nominated for the Academy Award and also won three Emmy Awards.
