Personal trainerCameron Paradise flees Hawaii and her abusive champion-surfer husband,Gregg, and makes her way to L.A. With her to-die-for looks, it doesn't take Cameron long to find a job at an exclusive private fitness club. Every man she meets comes on to her, but Cameron is more focused on opening her own studio one day than getting caught up in the L.A. scene of wild parties and recreational drugs.

Then Cameron meetsRyan Richards,a successful movie producer who happens to be married toMandy, the princess daughter of Hollywood mogulHamilton J. Heckerling. Ryan has never cheated on Mandy, but after he meets Cameron, all bets are off--even if she's seeing his best friendDon Verona, the devastatingly attractive talk-show host and legendary player.
