Plot
Ad man Steve Brooks — a promiscuous misogynist and quintessential chauvinist — is invited to a deadly surprise party by three former lovers. Margo, Liz and Felicia try to drown him in the hot tub. When that fails, Margo shoots him point blank in the chest, killing him.
In Purgatory, God (communicating through male and female voices) gives Steve one chance at redemption. He is returned to Earth, alive, and told that he must find a soulmate who truly loves him. If he fails, he will go to Hell.
The Devil convinces God to give Steve a challenge, taking his infamous charm into account, and Steve is transformed into a beautiful woman, Amanda. Amanda goes to Margo, convinces her of her real identity as Steve and persuades her to give her lessons in being a woman.
