In the final chapter of François Truffaut's saga, we find Doinel (Jean-Pierre Léaud), now in his thirties, convivially concluding his marriage, enjoying moderate success as a novelist, and clinging to his romantic fantasies. The newly single Doinel finds a new object of his affections in Sabine, a record store salesgirl whom he pursues with the fervid belief that without love, one is nothing.
