At a swanky café in midtown Manhattan, three twenty-something gals convene to discuss how to achieve their ultimate fantasy: becoming lusciously sexy, irresistibly seductive mistresses to supremely wealthy older men. Founders of their very own Mistress Club -- Brooke, a confident brunette; Delia, a feisty blonde; and MJ, an ambitious, red-haired siren -- have sworn off unsatisfying one-night stands, vowing to take control of their sex lives. And thanks to Brooke, they have a set of guidelines for becoming elegant mistresses:

Get first, then give
Don't waste your time on anything that won't get you something in return
Always dress to kill -- stilettos are a must!
Be discreet, aloof, mysterious, elusive
Don't get invested in him -- let him invest in you
And most of all, do NOT fall in love.

Armed with these rules, the three find themselves exactly where they wanted to be--in the arms of a generous, wealthy lover--and yet something vital is missing. To make matters worse, they each discover that their lovers have a dirty little secret--little enough for a mistress to ignore--but dirty enough to tear apart what matters most, forcing them down a path that will test their friendship and take them on a desperate mission to clear their names.
