The Post tells the story of the Washington Post's battle to publish the Pentagon Papers after the New York Times was served with an injunction by the Nixon adminstration. The fight takes place at a sensitive time, just as Katherine Graham is attempting to take the paper's owning company public. Much of the film's tension comes from the interplay between Graham and Ben Bradlee, the Post's tough editor, who is determined to publish when a second copy of the papers falls into his lap. Eventually, in a pivotal moment, Graham, under pressure from other members of the board who are worried that publication will spook the company's new investors, has to decide whether to side with Bradlee or whether to play it safe. In a nice final moment, the film concludes with a security guard discovering a break-in at the Watergate Building.
Needless to say, with a starry cast and a big name director, the film was always going to be good, but it does an excellent job of conveying the broad brush history of the Pentagon Papers — about which I have to admit a profound ignorance! I think it would be interesting to go back and watch All the President's Men, which features some of the same historical figures...
