The children devise a plan to retrieve the notebook from Guy: Lyes has to get it without being noticed. Time is running out, and Khadidja’s meeting with Nejib is approaching fast. But the plan goes awry when Guy’s father arrives unexpectedly and recognizes Lyes. The young messenger returns empty-handed, much to Khadidja’s despair. Philippe then decides to take matters into his own hands and proposes to win back the notebook fair and square in a boxing match with Guy.
