A filmmaker and his crew try to enter the passionate world of Port-Royal and of Jansenism. Another Age of Louis XIV comes to life, the age of Pascal, Racine and of the “Friends of Truth”. An age much darker and deeper than the splendors of Versailles. Through the landscapes of Port-Royal and Paris, thanks to the reading of texts in the French language of the time, thanks to interviews with specialists and to notes, the historical quest changes into a philosophical and historical vertigo. The film itself turns into something else while it comes up against the unanswerable question of grace.
