Six children aged from kindergarten to the fifth grade share their excitement for the new school year, from meeting new teachers and friends to preparing to leave in the morning. Ethan is nervous about starting Kindergarten. First grader Zach is worried about having to learn everything all over again. Katie finds out that their second-grade teacher's name starts with "Mr." It turns out that Jackie isn't the only third grader who gets dropped off early each morning. Carlos notices only a few other fourth graders who look like him. Fifth grader Mia takes time to adjust her hearing aids and is almost late.
