Steve Bannon's rise from Breitbart provocateur to chief strategist inside Donald Trump's White House anchors this film's account of the 2016 election and its aftermath. It traces how Bannon, more than almost anyone else in the Republican coalition, saw the populist opening Trump represented and worked to build a nationalist movement around it, from campaign strategy sessions to the internal power struggles that followed the inauguration. Interviews and news footage track his relationships with other Trump advisers, the ideological battles over immigration and trade that defined the administration's early months, and his eventual departure from the White House. The film treats Bannon less as a side character than as an architect, following the through-line from his media career to the policies and rhetoric that shaped Trump-era politics, and asking what his network of allies and outlets meant for the Republican party going forward.
