During a seaside holiday, Geneviève, a young woman from Paris, meets Daniel, a sailor. Their brief encounter blossoms into a tender love affair shaped by the rhythms of summer. When the season ends, distance separates them: Daniel returns to his life in Brest, while Geneviève resumes hers in Paris. Through letters and memories, their relationship persists across time and space. Blending moments of everyday life with images of the sea and the city, the film quietly reflects on absence, desire, and the fragile nature of love when sustained only by waiting and remembrance.
