The story of Danie Mallet, a young filmmaker (Jean-Luc Bideau) who is attempting to put his real life into a movie; his interactions with the people in the movie he is filming create reverberations in his "real" life, although the past remains unchanged. Among the complications is his growing regard for the woman who plays his cinematic wife (Jane Birkin). She may wind up replacing his actual wife in real life. One of the highlights of this film is the insight it gives into the actual mechanics of filmmaking.
