Monsieur Cinema, a hundred years old, lives alone in a large villa. His memories fade away, so he engages a young woman to tell him stories about all the movies ever made.

The first emotions in love with a young man of seventeen: Thomas who understands that his life belongs to him at last. Four young women contribute to his sentimental education.

Guy, film critic of the Cahiers du Cinéma and terminal cinephile, plans to write about the Vittorio Cottafavi retrospective at the Alcazar, his local cinema. One day he notices that Jeanne, film critic of Postif, the rival magazine, seems to be following him. He is intrigued-- is she interested in him, or planning to poach his praise for Cottafavi in her own article?
