This early, thirteen-minute short 'about' Charlotte and her 'jules' (or boyfriend) Jean is in effect almost entirely a monologue by Jean-Paul Belmondo* in his bedsit where Charlotte (Anne Colette) has returned after leaving him for another. He talks all the time, insults her lover, tells her she loves him, won't let her say a word while she makes faces at him behind his back and a guy (in fact Gérard Blain) waits for her in his car outside. Belmondo says she must love him or why has she returned? She opens her mouth to say 'To pick up my toothbrush', which she does and walks out the door.
*The voice we hear isn't in fact Belmondo's but Godard's, although there's some bad lip-syncing.
