Human Desires (1997)

Alicia Royale is a fashion mogul who decides to have a large pajama themed party as a promotion for her new line of clothing. At the party, the leading contender for the company spokesmodel is found dead in the swimming pool, apparently by suicide. Zoe Taylor does not agree and hires a private investigator named Dean Thomas to look into the death. Dean digs deeper and deeper into the world of modelling and finds out that it is a lot more than just taking pictures and smiling.
