Chose Secretes/Secret Things (2002)

This French film is like a distaff version of "In the Company of Men".  In that earlier film two male executives decide to entice a likely female to fall in love with them, just so they can then turn around and dump her -- it's supposedly just a game to them (although there are several twists which make it an interesting movie).  In this French flick, a sacked exotic dancer hooks up with a somewhat inexperienced young woman.  They live together and the former teaches her disciple how to use sex to enslave men and gain the upper hand in any relationship.  They insinuate themselves into a large company and do whatever is necessary to land the ultimate prize - the young boss and heir apparent.  However he has sexual agendas of his own including an incestuous relationship with his sister and the final fate of the main characters is not one that could have been guessed in advance.  Frankly, I found this film singularly unappealing and the lashings of sex did little to disguise the nasty undertones.
