In this spoof of Robert Louis Stevens classic novel comes a very fine comedy with Tim Daly and Sean Young. Dr. Richard Jacks(Daly), is a man who creates perfumes for companies. One day he discovers a journal belonging to his great grandfather, Dr. Henry Jekyll, that talks about a revolutionary discovery. Deciding to follow in his great grandfathers' footsteps, he creates a formula and after using it on himself, turns into a woman who he calls Ms. Helen Hyde(Young). Pretty soon, Helen begins to take over not only Richards' job but also his life. Much to Richards' chagrin is also the fact that Helen is now starting to appear without use of the formula and if he doesn't find a way of getting rid of her, he will vanish for good.
