When freshman Rusty (Jacob Zachar) gets to college, hes looking forward to the fun of parties and girls. But even as he tries to join a fraternity, he cant leave his geeky ways behind. His sweetly uncool manner gets him noticed, for better and worse, and soon, Rustys a GREEK. Serving as the shows moral center amid the depravity that the college Greek system is widely (and somewhat stereotypically) known for, Rusty stands up for himself and his shallow, mean sister, Casey (Spencer Grammer, Kelseys daughter), and even tolerates his strange roommate, all while studying in a world-class engineering program.
