The Panama Papers is a documentary that chronicles one of the largest data leaks in history: 11.5 million confidential documents from the Panamanian law firm Mossack Fonseca , released in 2016 by an anonymous source known as "John Doe." The film focuses on how a small group of journalists from the Süddeutsche Zeitung and the International Consortium of Investigative Journalists (ICIJ) worked under immense pressure to verify and publish the story.
