Clara Sheen is a well-known rebel at school who lives for practical jokes and visits the principal's office more often than any other student. When another prank goes too far and threatens suspension, her father “sentences” her to work at the family food truck. The punishment is made more severe by the fact that the best student of the school, Rose Carver, must be next to her all summer, and a handsome but overly correct guy named Hamlet appeared in the coffee shop opposite. Claire considers this pastime boring, not even suspecting that this summer could become the most important in her life.
