Think of this drama series as a kinder, gentler ``Revenge of the Nerds.'' It centers around a college freshman, Rusty, who's determined to shed his high-school geekiness and become a frat boy. Unfortunately, his older sister, Casey, is a sorority queen who isn't thrilled about having her kid brother in her Greek system. Rusty's roommate and fellow nerd, Dale, wants nothing to do with the fraternity scene but wouldn't mind getting to know Casey better. Casey's BFF is Ashleigh, who has good looks, a sunny disposition and terrible taste in men.
