Love in the Post is inspired by the book The Post Card by Jacques Derrida. Like the book, the film plays with fact and fiction, weaving together the stories of a scholar of literature and a film director, alongside insights from critics and philosophers. Theo Marks works in a university department that is soon to be closed. His wife Sophie, enigmatic and distant is in analysis. Filmmaker Joanna struggles to complete a film about The Post Card. These people are set on a collision course prompted by a series of letters that will change their lives. The film features a never before seen interview with Derrida, alongside contributions from Geoff Bennington, J. Hillis Miller, Sam Weber, Catherine Malabou and Ellen Burt.
