Based on the true story of the most famous anonymous man in American history: Mark Felt, the FBI second-in-command who was the "Deep Throat" whistleblower in the 1970s Watergate scandal. Few know about the personal and professional life of the man who risked sacrificing everything, including his family, career, and ultimately his freedom, to bring what he knew to light. The film shows us Watergate as we've never seen it before, flipping the perspective from All the President's Men's journalists-on-the-street to a view from the highest offices of power, an extraordinary window into a government in turmoil.
