 Stephane and Maxime run a well-respected violin making and repair business. When man-about-town Maxime falls in love with violin virtuoso Camille, Stephane - whose only attachment is a platonic one with a bookshop owner - takes his own interest in this new girl in Maxime s life and in her music-making. Camille gradually becomes attracted to him, but finds his cold lack of response by turns puzzling and irritating. Bit by bit the odd ménage-à-trois becomes set on a collision course.
