It's time for the new school year to begin. Stephanie is going into kindergarten, and D.J. and her best friend Kimmy Gibbler are going into 5th grade. Stephanie has a severe case of the kindergarten jitters because she's afraid her new classmates will reject her, so it's up to D.J. and the guys to help Stephanie. Later, D.J. also wants to avoid school when she and Kimmy are placed in separate classrooms.
