On Children's Day, the students are all excited. The principal tells them that they can do whatever they want with their day. They'll watch a movie or take a test. The students are so excited that they run out of pens and pens are already running out, so they go to the pawnshop to buy pens. The other students are getting ready for their snacks, so the students run off to buy snacks. The teacher tries to cheer them up by telling them that the father of the students has been training them for a month, but now that they're all watching a movie, he's trying to impress them. The children are so upset that they lie and say that their class will watch a 5-hour documentary on "ecological tourism" instead of a movie. The teachers are so shocked that they decide to make a short film about baking cookies to get the students excited.
