Watch Sister My Sister

In this drama/thriller, a woman works as a maid for a wealthy woman and her teenage daughter. When the maid's long-estranged sister comes to work for the household, too, the tensions and fraught relationships result in resentment, forbidden sexual encounters, and, eventually, violence. The film stars Joelly Richardson and Jodhi May. It was based on a true story that took place in France in the 1930s.
