Director Emmanuel Laurent tells the story of directors François Truffaut and Jean-Luc Godard, their friendship with each other, and their working relationship with the young actor Jean-Pierre Léaud. Both Truffaut and Godard were critics at Cahiers du Cinema. Both became filmmakers and both took the world by storm, just one year apart, with their debut films The 400 Blows and Breathless. Léaud appeared in several films by both filmmakers. But toward the end of the 1960s, Truffaut and Godard had a major falling-out over politics and filmmaking, and never spoke again. Léaud was caught in the middle.
