Annabelle is so excited for the summer to begin. On the last day of school, she finds it very hard to participate in the class activities. She comes up with a plan to end the school day earlier by changing the time on the classroom clock to set off the bell! This causes more havoc than she thought possible. The class pet breaks free; Miss Jones tries to catch the gerbil who runs into the hallway, and poor Principal Jones trips and falls! Annabelle learns of patience during this mischievous and a little embarrassing lesson.
