All over Hollywood, men are dialing O--for orgasms. Her steamy naughty talk fills them with lust and longing, and helps them perform like the studs they claim to be.

In truth, the industry's favorite "erotic phone operatrix" is Nina Harte, a struggling actress who has put her career on hold so that her husband, Nathan, can pursue his own dreams of stardom. When Nathan's career takes off, so does he, leaving Nina and their four-year-old son, Jake, for his diva costar, Katerina McPherson. Then "Kat 'n' Nat" are crowned the media's newest celebrity sweethearts, and Kat labels Nina an unfit mother in order to win custody of Jake, just so that she can have that highly-coveted celebrity accessory--an adorable child--sans any unsightly stretch marks.

The one person who does care about Nina is Nathan's agent, Sam Godwin. In fact, he's in love with her. And because he has both a heart and a conscience, Sam feels guilty for having put Nat in Kat's path in the first place . . .

Then again, how will he feel when he learns that Nina and O are one and the same?
