The Other Side of Julie (1978)

Julie's husband Mike has an extraordinary lifestyle - a white Rolls-Royce Corniche convertible, a large business, a magnificent home, and a side line that Julie knows nothing about. He selects lovely young women at random, and makes the following proposition: he will supply the financial backing for a new business partnership and in return the girls supply him with a share of the profits and unlimited sex! When Julie finally discovers Mike's sham, she turns the tables and takes over.
