Jack Python, Howard Soloman, and Mannon Cable have been competitive friends for years. Yet when Jade Johnson enters their lives, the least-expected one of the self-styled ''Three Comers'' may have finally met his match. Jade Johnson is a woman of the eighties. Strong, independent, a top New York model, she comes to L.A. for a series of million-dollar TV commercials. Jade is a dangerously beautiful woman with personal integrity and a mind of her own. The Hollywood game fails to impress her, but slowly, surely, she is sucked in. And, high roller that she is, if she must play, Jade will play to win.

NOW HOLLYWOOD HUSBANDS GO ALL THE WAY!
