In the 23rd century, Zoe, a historian, discovers the diaries that a middle-class architect, Harry Roberts, wrote in 2016 and decides to recreate his life.
Harry, an ardent remainer, meets Michelle by chance. Like most people she knows, Michelle voted leave. The two are drawn to each other despite their differences and begin a relationship.
Writing in a bleaker, climate-ravaged future, from which the political concerns of the today seem very remote, Zoe turns this personal story into a reflection on the divisions we face, the ideologies we prioritize and questions: what next?
