When the Playboy Mansion's favorite bunny, Shelly (Faris) is kicked out by a rival, she gets lost in the wilderness of Beverly Hills. She stumbles into the sorriest sorority on campus, Zeta Alpha Zeta. The seven cluesless women of the sorority need her. Unless they can sign a new pledge class,they will lose their house to the scheming girls of Phi Iota Mu. In order to accomplish their goal, they need Shelley to teach them the ways of makeup and men; at the same time, Shelley needs some of what the Zetas have -- a sense of individuality. The combination leads all the girls to learn how to stop pretending and start being themselves.
