Code 68 (2005)

Anne Buridan, a woman in her thirties who thrives on challenges, takes on the project of making a film about the events of May 68. The task is difficult not only because she's delving into unfamiliar history, but also because her boyfriend, Blaise, strongly dislikes the people involved. Methodical and determined, Anne presses forward with her project, connecting with figures from that era, starting with a woman who mentions Jean-Pierre Lucciani. The name rings a bell for Anne, as it’s the same as Blaise’s. She discovers Jean-Pierre is indeed Blaise's father. Returning home, Anne keeps this discovery from Blaise, unknowingly losing control of the situation.
