She recruits the help of a boy named Bank, who is intelligent but has money problems. Together, they devise a plan to cheat on the exam, using a complex system of barcodes and hidden answers.
However, things don't go as planned, and Lin is forced to improvise to avoid getting caught. She manages to send the answers to her classmates, but not before being caught by security.
