It follows the reporters and editors of the NY Times through their process. The Trump White House is a huge component of their work. But they also cover significant stories outside of that: the impact of policy shifts from the administration (both positive and negative) throughout the country, Americans' perception of Washington and the media, the sexual harassment claims against people like Bill O'Reilly and Harvey Weinstein, along with the violence in Charlottesville, VA.
Additionally, it deals with some of the BUSINESS of the Times: an earnings conference call, shifts from print to online content, the immediacy of deadlines, as well as a walkout of a tremendous number of newspaper guild members because of restructuring at the Times. You also get a sense of the toll that the work takes on these journalists: extremely long work hours, the toll it takes on their families, or their personal isolation because the work is so demanding.
Watching Times reporters asking questions of their sources and interview subjects, it becomes very clear that these journalists take the work incredibly seriously. And they choose their words VERY carefully. They ask questions VERY carefully. It addressed how the Times works to keep their own house in order: harassment charges, social media policy, etc. It also shows how some political figures who routinely like to use the media as a punching bag are also incredibly chummy with reporters. Watch Times political reporter Jeremy Peters interact with Steve Bannon and their interactions. It's enlightening.
As for anything beyond that? The audience is left to make that judgement for themselves.
