My Mistress 2014

My Mistress is a 2014 Australian drama, starring Emmanuelle Béart and Harrison Gilbertson. A traumatized teenager meets a mysterious French woman, who turns out to be an S&M Mistress. I saw this when it came out, it's really more a coming of age drama with a fetish backdrop but Emmanuelle Béart is amazing.
