After the death of his grandmother Emma, Robin Hunzinger and his mother Claudie find a carefully preserved collection of letters which Emma received from a girl called Marcelle. In the 1920s, Emma and Marcelle met at school in Dijon. Secretly, love blossomed between the two teenage girls, but after two years they parted ways. Marcelle developed tuberculosis and was admitted to a sanatorium. Complementing the sparse photographs of the women, Hunzinger combines archive footage, avant-garde films, and music to create a sensuous, poetic atmosphere.
