The family and staff unsuccessfully try to prevent Graves from finding out that his attempted assassin Martin Treadwell (while he was in the White House 25 years ago) is seeking a furlough to visit his dying mother. Graves attends his gardener's niece's quinceañera and becomes an advocate for the Mexican immigrant community. Margaret is approached by the Republican Party and invited to launch a Senate campaign, while Isaiah and Olivia get too close for (Isaiah's) comfort.

Graves is forced to acknowledge that his views are on the wrong side of history as he reluctantly attends his speechwriter's marriage…to another man. Meanwhile, Olivia falls deeper in love with Arturo and Margaret gets a surprising call from an old friend with benefits, tech billionaire Jonathan Dalton. Isaiah tries to prep Jeremy for a local morning news show but he's more interested in throwing a party.
