President Franklin Roosevelt prepares to welcome King George VI and his wife Elizabeth to America.
Feverish media interest is glimpsed through the eyes of Daisy (Laura Linney), who describes herself as fifth or sixth cousin to the president.
Living in obscurity with her aunt (Eleanor Bron), Daisy is unexpectedly summoned to the side of the 32nd president (Bill Murray) in the hope that she can take his mind off the hoopla surrounding the British royals (Samuel West, Olivia Colman).
Amid the whirl of activity, Daisy develops a close bond to Franklin and they become lovers.
However, Daisy isn’t Franklin’s only means of distraction and she must learn to share the man in power with others in his social circle.
