It's Greek week at Mali-U and Clover is psyched because she's going to pledge a new sorority, Phi Epsilon Phi, or PEP for short. Sam and Alex aren't too interested, especially when they discover that Mandy and her equally obnoxious cousin Mindy, whom... (more) the girls find out go to their school, are both PEP hopefuls! And the leader has a sinister plan which involves brainwashing her cronies! In a b-story, the girls each try to find a university activity to join.
