Greg Heffley is looking forward to his birthday — he dreams of a big surprise party full of cake, friends, and the one rare trading card he really wants. But things start badly when his parents completely forget his birthday. When the family realizes their mistake, they decide to throw him a huge “make-up” party in the backyard. Greg’s plans for a perfect celebration go into overdrive: he schemes to make as much money as possible at the party so he can buy the rare trading card, charging people for Kool-Aid, toilet paper, and more. But as expected for a Wimpy Kid story, the party spirals into chaos — decorations go wrong, unexpected guests turn up, and his grand plans clash with reality. In the end, Greg does get the card he wanted, but he finds out it’s no longer rare because it’s become so popular. Still, not all is lost: Greg launches a side hustle of hosting parties, learning that even when things don’t go your way, you can turn disaster into opportunity.
