Original title (FR): Ombres de soie (Silken Shadows)

Shades of Silk is a film of mood and memory; two Chinese women, who had been friends in school, are caught between a longing for social stability and something much more fulfilling but frightening and vague in their relationship. A large part of the action takes place in the Shanghai of 1935 although the film was shot entirely on location in Paris.
