The USA is in a state of Civil War and everything points to a secessionist victory. Renowned War photographer Lee (Kirsten Dunst) and journalist/fixer Joe (Wagner Moura) plan to take a circuitous route to Washington DC avoiding most of the fighting and to _try_ to interview the President before the fall of the Capitol. This is considered a near suicidal endeavour by senior journalist Sammy (Stephen McKinley Henderson) but he nonetheless takes a spot on their truck.
While photographing a food riot Lee encounters a young woman, Jessie (Cailee Spaeny), who wants to be a journalist and is carrying around an old film camera.
Expecting never to see her again, the following morning Lee finds Jessie in the last seat in the truck: she has persuaded Joe to let her tag along.
No good will come of this.
